binder: fix up use of MAX_USER_RT_PRIO

Browse source 
Commit e00eb41c0c7b ("ANDROID: binder: add support for RT prio
inheritance.") added the use of MAX_USER_RT_PRIO to the binder.c code,
but that commit was never sent upstream.

In commit ae18ad281e82 ("sched: Remove MAX_USER_RT_PRIO"), that define
was taken away, so to fix up the build breakage, move the binder code to
use MAX_RT_PRIO instead of the now-removed MAX_USER_RT_PRIO define.

Hopefully this is correct, who knows, it's binder RT code!  :)
