seccomp: add semctl() to the syscall whitelist

QEMU needs to call semctl() for correct operation. This particular
|
|
|
9ae3a8 |
problem was identified on shutdown with the following commandline:
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
# qemu -sandbox on -monitor stdio \
|
|
|
9ae3a8 |
-device intel-hda -device hda-duplex -vnc :0
