[FYI] {maint} tests: list some forgotten test cases in $(TESTS)

[Stefano Lattarini]

This way, they will be properly executed by "make check", and
properly distributed.  Our previous commit 'v1.11-647-g27f1a1c'
is already paying its dividends!

* tests/list-of-tests.mk (handwritten_TESTS): Add check12.test,
dist-missing-included-m4.test, dist-missing-am.test, and
dist-missing-m4.test.
