[PATCH 08/23] linux: Simplify sched_rr_get_interval

[Adhemerval Zanella]

With arch-syscall.h it can now assumes the existance of either
__NR_sched_rr_get_interval or __NR_sched_rr_get_interval_time64.
The 32-bit time_t support is now only build for
!__ASSUME_TIME64_SYSCALLS.

Checked on x86_64-linux-gnu and i686-linux-gnu (on 5.4 and on 4.15
kernel).
