linux: Simplify ppoll
With arch-syscall.h it can now assumes the existance of either __NR_ppoll or __NR_ppoll_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). Reviewed-by: Lukasz Majewski <lukma@denx.de>
