[4/5] nptl: Convert some rwlock tests to use libsupport
Commit Message
* nptl/tst-rwlock6.c: Use libsupport. This also happens to fix a
small bug where only tv.tv_usec was checked which could cause an
erroneous pass if pthread_rwlock_timedrdlock incorrectly took more
than a second.
* nptl/tst-rwlock7.c, nptl/tst-rwlock9.c, nptl/tst-rwlock14.c: Use
libsupport.
