sysvipc: Return EINVAL for invalid msgctl 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).
