Remove unnecessary getpriority() system call 

This was introduced for a valid reason in aosp/1224543, but that reason
was later removed. This code wasn't.

It is not worth making a system call in order to possibly avoid a second
one, which I expect is no more expensive in that, particularly easy,
case.
