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. Reviewed-by: Florian Weimer <fweimer@redhat.com>
