runtime: skip test that intermittently hangs on ppc64le

Browse Source 
A new testcase TestSelectFairness was recently added, and
since then the ppc64le build tests have intermittently failed.

This adds a change to skip this test on ppc64le using
SkipFlaky to help determine if the problem is with the
test or something else with that commit.

Updates #22047
