"THE REST" maintainers should always be CCed for any modification that
don't fall under the responsability of a specific component maintainer.

However, the script get_maintainers.pl will remove "THE REST"
maintainers as soon as one maintainer of a specific component will be
present.

Fix the script once for all.

I am getting annoyed at requesting contributors to CC "THE REST" because
the script didn't properly return the list of maintainers. This should
now be fixed.
