s390/syscalls: Convert filechk to if_changed

The filechk macro always executes the syscalltbl script (and discards
the output if there are no changes).

Using if_changed is more efficient because it avoids running the script
when the target is up-to-date and the command remains unchanged.

All other architectures use if_changed for generating syscall headers.
