Coin: Extend VxWorks restart matching to RTPLib errors

Running many tests on the VxWorks in the emulator without
restarting it between can cause exhaustion of some
resources and cause an RTP spawn fail in some tests.

This change will restart the emulator in such cases, which
allows the test to try again on fresh boot.
