[PATCH v2 2/3] Makefile: remove UNIT_TEST_BIN directory with "make clean"

[Jeff King <peff@peff.net>]

We remove $(UNIT_TEST_PROGS), but that leaves the automatically
generated "bin" dir they reside in. And once we start cleaning that,
there is no point in removing the individual programs, as they'll by
wiped out by the recurse "rm".

The layout of the clean rule is kind of weird, in that we put only
sort-of related things together on their own $(RM) line. I suspect a lot
more of this could be lumped together, reducing the total number of
shells and rm invocations needed, but I guess nobody really cares that
much about the runtime cost of "make clean".
