SCRIPTS: git-show-backports: re-enable file-based filtering 

The early version of the script used to support passing non-branch
arguments but as it evolved we lost that option. Let's use "--" as a
delimiter after the branch(es) to pass optional file names to filter
on. This is convenient to list missing patches on a specific set of
files.
