examples/, locale/, and thread/ lacked .gitignore files and were also
not connected up to top-level "make clean" etc. This had escaped notice
because none of those directories are built in normal scenarios. Still,
they have working Makefiles, so if someone does a "make" in one of these
directories it would be good if (a) git doesn't bleat about the product
files and (b) cleaning up removes them.
This is a longstanding oversight, but since this behavior is probably
only of interest to developers, there seems no need for back-patching.

It's not run by the global "check" or "installcheck" targets, because the
temporary installation it creates accepts TCP connections from any user
the same host, which is insecure.
This is advance preparation for introducing even more test modules; the
easy solution is to add them to contrib, but that's bloated enough that
it seems a good time to think of something different.
Moved modules are dummy_seclabel, test_shm_mq, test_parser and
worker_spi.
(test_decoding was also a candidate, but there was too much opposition
to moving that one. We can always reconsider later.)
