[Ada] Fix Ada-QNX task priority conversion

The conversion between OS and Ada priorties should be done in the wider
Interfaces.C.int type rather than Any_Priority otherwise
Constraint_Error will be raised when coverting Any_Priority'Last to int.

gcc/ada/

	* libgnarl/s-osinte__qnx.adb (To_Target_Priority): Perform
	arithmetic in int.
