get_maintainer.pl: fix source tree detection

get_maintainer.pl always fails with following message:
./scripts/get_maintainer.pl: The current directory does not appear to be a linux kernel source tree.

This was caused by commit:

commit 548b310c68ac99a0330d8b56c797c09ff0742d1e
Author: Masahiro Yamada <yamada.m@jp.panasonic.com>

    Remove the CREDITS file

    This file is not maintained these days.

    We use MAINTAINERS for the maintainership of the supported boards.
    For dead boards, we have some clues in doc/README.scrapyard and
    also imperishable history in git-log.

Remove CREDITS from source tree detection to fix this.
