seccomp: add shmctl(), mlock(), and munlock() to the syscall whitelist
Additional testing reveals that PulseAudio requires shmctl() and the
mlock()/munlock() syscalls on some systems/configurations. As before,
on systems that do require these syscalls, the problem can be seen with
the following command line:
# qemu -monitor stdio -sandbox on \
-device intel-hda -device hda-duplex
