tests/tcg: Skip failing ppc64 multi-threaded tests

In Gitlab CI, some ppc64 multi-threaded tcg tests crash when run in the
clang-user job with an assertion failure in glibc that seems to
indicate corruption:

  signals: allocatestack.c:223: allocate_stack:
    Assertion `powerof2 (pagesize_m1 + 1)' failed.

Disable these tests for now.
