Patrick Georgi 9110c17668 util/gitconfig: improve robustness of checkpatch in pre-commit
Users can have non-default configurations as to how git diff et al are
presenting file names in diffs (default: a/ and b/ prefixes). checkpatch
expects that and trims the first element, so enforce that configuration
for the diff that's sent into it.
