test-lib.sh: unset XDG_CACHE_HOME

git respects XDG_CACHE_HOME for the credential cache. So, we should
unset XDG_CACHE_HOME for the test environment, lest a user's custom one
cause failure in the test.

For example, t/t0301-credential-cache.sh expects a default directory
to be used if it hasn't explicitly set XDG_CACHE_HOME.
