build: allow update_build to generate fake version (#5098)

Browse Source 
When the build is done on a shallow repo, or on a non-git copy,
the version script failed. We should not hard fail, but generate
a "version" (unknown).

Sample outputs:

with git history:
`"v2023.2-dev", "SPIRV-Tools v2023.2-dev v2022.4-87-g53541064"`

with shallow clone:
`"unknown_version", "SPIRV-Tools unknown_version d8759a140bc65811332d5f91f3b08febadd5a21d"`

not a git repo:
`"unknown_version", "SPIRV-Tools unknown_version unknown_hash, 2023-02-02T16:25:48.077995"`
