timer: Decouple x86_64 specific timer_settime from generic Linux implementation
The x86_64 specific timer_settime implementation (from
./linux/x86_64/timer_settime.c) reused the Linux generic one (from
./linux/timer_settime.c) to implement handling some compatible timers
(previously defined in librt, now in libc).

As the generic implementation now is going to also support new (available
from Linux 5.1+) timer_settime64 syscall, those two implementations have
been decoupled for easier conversion.

The original INLINE_SYSCALL() macro has been replaced with
INLINE_SYSCALL_CALL() to avoid explicit passing the number of arguments.
