This feels a bit fragile since even just now I often fail to put a test
newly converted to the subtest stuff into the right single/multi make
target list. Also, this way we exclude a test by default, which also feels
like the wrong way round (most of the tests we're adding aren't heavy
stress-tests, but more excercise some corner-case).

So what about a sprinkling

drmtest_skip_on_simulation();

over the remaining testcases instead, which just calls exit(77);? Only
caveat is that for subtests we need to put it into the right spot to not
break subtest enumeration in piglit (it's a bit fragile).

Cheers, Daniel
