rfc.sh: use 'git log -n1' instead of 'git show'

This is required mainly because if we use any format in a
documentation, and it has strings which are looking for commit
msg format (like fixes: bz...) in document, that too will be
considered in checks, even though it is not part of commit msg.

By using git log -n1, we would only check the content of commit
msg.
