sysvipc: Return EINVAL for invalid semctl commands
It avoids regressions on possible future commands that might require
additional libc support. The downside is new commands added by newer
kernels will need further glibc support.
Checked on x86_64-linux-gnu and i686-linux-gnu (Linux v4.15 and v5.4).
