get_maintainer.pl: allow "K:" pattern tests to match non-patch text

Extend the usage of the K section in the MAINTAINERS file to support matching regular expressions to any arbitrary text that may precede the patch itself. For example, the commit message or mail headers generated by git-format-patch. Signed-off-by: Joe Perches <joe@perches.com> Original-patch-by: L. Alberto Giménez <agimenez@sysvalve.es> Acked-by: L.
