[PATCH v2] Mark mtrace tests UNSUPPORTED if bug-ga2.mtrace or tst-leaks2.mtrace are missing

[Stefan Liebler]

Starting with commit 29fddfc7dfd6444fa61a256e9a0d0127545e1f2e, the
tests posix/bug-ga2 and resolv/tst-leaks2 are test-container tests.

If test-container.c returns with EXIT_UNSUPPORTED, the tests with
mtrace() are not executed and the mtrace files do not exist.

Therefore the "mtrace-analysis-part" of those tests are marked
UNSUPPORTED if the mtrace files are missing.
