Deny (non-fatal) ipc in preauth privsep child.V_8_1
As noted in openssh/openssh-portable#149, i386 does not have have
_NR_shmget etc. Instead, it has a single ipc syscall (see man 2 ipc,
https://linux.die.net/man/2/ipc). Add this syscall, if present, to the
list of syscalls that seccomp will deny non-fatally.
