pkg/subsystem: recognize more maintainers

Earlier we only took maintainers if there was just one MAINTAINERS
record, but that was a very severe limitation.

Let's try a more elaborate approach. It's also not perfect, but allows
us to extract many more maintainers, while keeping false positives at
zero.

Group raw MAINTAINER records by their T: entries. If there's just one
set of T: values per group mailing list, take the intersection of M:
entries from there.
