Add more unimplemented syscall events
Added events for *ctl syscalls that may have multiple different commands. For runsc, each syscall event is only logged once. For *ctl syscalls, use the cmd as identifier, not only the syscall number. PiperOrigin-RevId: 218015941 Change-Id: Ie3c19131ae36124861e9b492a7dbe1765d9e5e59
