[PATCH] 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.

Notes:

  This is the XDG_CACHE_HOME version of 5adf84ebb ("test-lib.sh: unset
  XDG_CONFIG_HOME", 2012-07-24).
