abi_version/sstate: Handle pkgconfig output changes and bump output versions

A recent package.py change has highlighted some corruption issues with -dev
pkgconfig package dependencies. Bump the output versions to trigger a rebuild
and ensure everything is consistent.

Take the opportunity to also drop all HASHEQUIV_HASH_VERSION entries since the
main version is changing.
