scripts/get_maintainer.pl: use --git-fallback more often

Turns out this is an arguable defect in the script.
The MAINTAINERS entry for mm is:
MEMORY MANAGEMENT
L: linux-mm@kvack.org
W: http://www.linux-mm.org
S: Maintained
F: include/linux/mm.h
F: mm/
There's a maintainer entry, but no named individual, so the script doesn't
use git history via --git-fallback.
This is also a defect for MAINTAINERS with status entries marked "Orphan"
or "Odd fixes".
The script now checks a section for any "M:" entry and that an "S:" entry
is supported or maintained. If both those conditions are not satisified,
use --git-fallback as appropriate.
