futex: use current->time_slack_ns for rt tasks too

Browse source

RT tasks should set their timer slack to 0 on their own.  This
patch removes the 'if (rt_task()) slack = 0;' block in
futex_wait.

Build and boot tested on a 4 way Intel x86_64 workstation.
Passes basic pthread_mutex and PI tests out of
ltp/testcases/realtime.
