Ifdefed out deadcode in position_estimator_inav_main.c as the
deadcode does not compile for qurt.
Added fixes to get a successful build for posix-arm and qurt targets.
Removed CLOCK_REALTIME def from px4_time.h for qurt and removed unused
variables in att_est_q and mc_att_control.

Changed muorb_fastrpc.cpp to px4muorb.cpp to match the name of the
library that implements the FastRPC calls.
