Fix failing to set high priority for threads on Linux desktop. Debugging inside rtkit showed we were failing the RLIMIT_RTTIME check, now that we're asking for realtime and not just high-priority due to a change in SDL. Between that and the DBus code in SDL being wrong in previous changelist I'm not sure how this could have ever worked.
