[llvm] [PowerPC][test] Catch any exception when retrieving git revision (PR #92004)

[Jake Egan via llvm-commits]

https://github.com/jakeegan created https://github.com/llvm/llvm-project/pull/92004

This makes the `vc-rev-enabled` feature unsupported if we fail to retrieve the git revision for any reason, such as if git is not installed.
