[PATCH 2/2] git: Verify boolean values passed to sync-git-verify-commit-signature

Currently, if 'sync-git-verify-commit-signature' is set to anything
other than 'yes', 'no', 'true', or 'false', its value is ignored
silently and nothing is verified because the option defaults to 'false'.

Introduce a check to CheckGitConfig that warns the user if their input
is invalid.

Closes: https://bugs.gentoo.org/703698
