Bump the priority of the IPC receive queue in AuxiliaryProcesses

Reviewed by Per Arne Vollan.
Bump the priority of the IPC receive queue in AuxiliaryProcesses, to
match the priority of the main thread. This is important to avoid
priority inversion bugs when the main thread is doing a sendSync() and
the main thread is thus waiting on IPC.
This tested as performance neutral on the benchmarks we track.
