From: Eric Engestrom <e...@engestrom.ch>
Meson's vcs_tag() uses the output of `git describe`, eg.
17.3-branchpoint-5-gfbf29c3cd15ae831e249+
Whereas the other build systems used a script that outputs only the sha1
of the HEAD commit, eg.
fbf29c3cd1
Given that this information is used by printing it next to the version
number, there's some redundancy here, and inconsistency between build
systems.
Bring Meson in line by making it use the same script, with the added
advantage of now supporting the MESA_GIT_SHA1_OVERRIDE env var.
