sysvipc: Implement semop based on semtimedop
Besides semop being a subset of semtimedop, new 32-bit architectures
on Linux are not expected to provide the syscall (only the 64-bit time
semtimedop).
Also, Linux 5.1 only wired-up semtimedop for the 64-bit architectures
that missed it (powerpc, s390, and sparc). This simplifies the code
to support it.
Checked on x86_64-linux-gnu and i686-linux-gnu.
