bitbake: fetch2/git.py: Add gitpkgv_revision alternative version information 

gitpkgv_revision returns a sortable revision number that can be used
in the PKGV variable for example. To mimic meta-openembedded gitpkgv
behaviour to provide a sortable revision numner, one could set the
following:

PKGV = "1.0+${@bb.fetch2.get_srcrev(d, 'gitpkgv_revision')}"

This would yield a package version like "1.0+69+fb5eb80".

(Bitbake rev: 989c08f62aff7b707c25c692c23284f16506b7bc)
