devel: Remove SHA1 hashes for distfiles

Log message:
*: Bump PKGREVISION for ghc-9.0.1

Log message:
Update to happy-1.20.0

* Fix #121: the -i flag produces an .info file even if
  the %expect pragma is violated
* Fix #131: qualify uses of Prelude functions in generated code
* Fix #161: drop fewer parse items when generating an .info file
* Introduce the %shift directive to resolve shift/reduce
  conflicts explicitly, useful in conjunction with %expect 0
* Remove the deprecated build configuration flag 'small_base'

Log message:
Remove dependency on devel/hs-mtl

mtl is now a part of GHC.

No changes made to these distinfo files.

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

Log message:
Set BUILDLINK_DEPMETHOD.happy to "build" as happy is not a library but \ 
a build tool

Log message:
Import happy-1.19.5 as devel/happy,
packaged for wip by esg.

Happy is a parser generator for Haskell. Given a grammar specification in
BNF, Happy generates Haskell code to parse the grammar. Happy works in a
similar way to the yacc tool for C.
