oe-go-mod-fetcher: fix pseudo-version tag assignment in SRC_URI

Go's module cache .info files store Origin.Ref as the "nearest tag"
used to derive pseudo-versions (e.g., v0.0.0-20190215142949-d0b11bdaac8a
stores Ref: "refs/tags/v0.3.0"). This ref is NOT a tag pointing to the
pseudo-version's actual commit - it's just metadata about the base version.

The generator was blindly using this ref as tag=v0.3.0;shallow=1 in
SRC_URI entries. BitBake resolves the tag to one specific commit, finds
it doesn't match the rev= parameter, and fails with:

  FetchError("The revision the git tag 'v0.3.0' resolved to didn't match
  the SRCREV in use...")

This caused multiple SRC_URI entries for the same repo (e.g.,
go.googlesource.com/sys) to all claim tag=v0.3.0 but with different
rev= values - only one could possibly be correct.

Fix by detecting pseudo-versions via parse_pseudo_version_tag() and
clearing the ref_hint so these entries use nobranch=1 without a tag,
falling back to full clone by commit hash. Tagged versions (real
releases) correctly retain their tag= parameter for shallow clones.

The docker-compose .inc files are regenerated with the fix applied.
