Add git commit tag, hash and date to vendor string when available
In some circles (Hydrogenaud.io for example) people share binaries
compiled from git, i.e. inbetween official releases. Files created
with these binaries cannot be discerned from others. To improve
troubleshooting, compiles from a git repository are marked with
the commit hash and date when configured with autotools or CMake
