rados/test_crash.sh: add PG_DEGRADED to ignorelist

Issue: rados/test_crash.sh is failing due to PG_DEGRADED
state.

Cause: This is expected as we are intentionally killing OSDs
and testing for crashes. Adding the PG_DEGRADED warning to
the ignorelist will prevent the test from failing when this
warning is raised.
