[src/trunk]: src/usr.bin/make/unit-tests make(1): split test suffixes.mk into...

description:
make(1): split test suffixes.mk into simpler, isolated tests
The code in suff.c is already hard to understand, and so were the tests
in suffixes.mk since several independent topics were merged into a
single test.
Splitting this test into a separate test per issue allows to document
the expected and actual behavior in more detail. That's complicated
enough already.
