glibc: Skip 2 qemu tests that can hang in oe-selftest

qemumips and qemuppc were leaving stale processes behind after
running glibc oe-selftest. During analysis, it was found that
it was due to "tst-scm_rights" and "tst-scm_rights-time64" tests.
Disable them so that there are no stale processes left behind.
