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.
