Bump PKGREVISIONs for perl 5.30.0

Log message:
Recursive bump for perl5-5.28.0

Log message:
*: Move SUBST_STAGE from post-patch to pre-configure

Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.

Log message:
Remove mk/find-prefix.mk usage from the parallel category.

The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.

Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure.  Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.

Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

Log message:
Add SHA512 digests for distfiles for parallel category

Existing SHA1 digests verified, all found to be the same on the
machine holding the existing distfiles (morden).  Existing SHA1
digests retained for now as an audit trail.
