Ignore PSHM warning when testing co-locales on GASNet (#26611)

Ignore PSHM warning when testing co-locales on GASNet. GASNet will print
a warning if PSHM is disabled and there are multiple processes on the same
node (i.e., there are co-locales). This warning should be ignored when
checking test output.
