package/uclibc-ng-test: disable tst-cond22 with glibc based toolchain

uclibc-ng-test is broken with glibc 2.25 due to pthread_cond_t changes
introduced by [1].
Waldemar has disabled this test (tst-cond22) with glibc based toolchain
[2] but the current uclibc-ng-test package doesn't contain this patch.

So here it is.

Fixes:
