meta: bump HASHEQUIV_HASH_VERSION after RPM fix

ef37fca2 fixes issues where PLATFORM tag in RPMs generated
n aarch and x86 hosts are different for noarch RPMs. But, we'd
still need to bump hashequiv version for allarch recipes
to avoid issues because of the RPMs that were incorrectly
generated so reproducibility tests don't fail. Also bump PR
to force rebuilds.
