libgit2: manually drop -Werror with BUILDLINK_TRANSFORM

There is an ENABLE_WERROR cmake arg which is default OFF so I guess
the package logic for this is broken.

v1.6
----

This is release v1.6.0, "Hubbeliges Krokodil". This release adds \ 
experimental SHA256 support and includes many new features and bugfixes.

## What's Changed

### New features

* **Support for bare repositories with SHA256 support (experimental)** by \ 
@ethomson in https://github.com/libgit2/libgit2/pull/6191
   You can configure experimental SHA256 support in libgit2 with `cmake \ 
-DEXPERIMENTAL_SHA256=ON` during project setup. This is useful for considering \ 
future integrations, work on clients, and work on language bindings. At present, \ 
working with bare repositories should largely work, including remote operations. \ 
But many pieces of functionality - including working with the index - are not \ 
yet supported. As a result, **libgit2 with SHA256 support should not be used in \ 
production or released with package distribution.**

* **Support the notion of a home directory separately from global configuration \ 
directory** by @ethomson in https://github.com/libgit2/libgit2/pull/6455 and \ 
https://github.com/libgit2/libgit2/pull/6456
  Callers and language bindings can now configure the home directory that \ 
libgit2 uses for file lookups (eg, the `.ssh` directory). This configuration is \ 
separate from the git global configuration path.

* **stash: partial stash specific files** by @gitkraken-jacobw in \ 
https://github.com/libgit2/libgit2/pull/6330
  A stash can be created with only specific files, using a pathspec. This is \ 
similar to the `git stash push` command.

* **push: revparse refspec source, so you can push things that are not refs** by \ 
@sven-of-cord in https://github.com/libgit2/libgit2/pull/6362
  Pushes can be performed using refspecs instead of only references.

* **Support OpenSSL3** by @ethomson in \ 
https://github.com/libgit2/libgit2/pull/6464 and \ 
https://github.com/libgit2/libgit2/pull/6471
  OpenSSL 3 is now supported, both when compiled directly and dynamically loaded.

Log message:
devel/libgit2: update to 1.5.1

1.5.1 (2023-01-20)

libgit2, when compiled using the optional, included libssh2 backend, fails
to verify SSH keys by default.

Description

When using an SSH remote with the optional, included libssh2 backend,
libgit2 does not perform certificate checking by default.  Prior versions of
libgit2 require the caller to set the certificate_check field of libgit2's
git_remote_callbacks structure - if a certificate check callback is not set,
libgit2 does not perform any certificate checking.  This means that by
default - without configuring a certificate check callback, clients will not
perform validation on the server SSH keys and may be subject to a
man-in-the-middle attack.

Beginning in libgit2 v1.4.5 and v1.5.1, libgit2 will now perform host key
checking by default.  Users can still override the default behavior using
the certificate_check function.

The libgit2 security team would like to thank the Julia and Rust security
teams for responsibly disclosing this vulnerability and assisting with
fixing the vulnerability.

Users are encouraged to upgrade to v1.4.5 or v1.5.1.
