seccomp: add mkdir() and fchmod() to the whitelist
The PulseAudio library attempts to do a mkdir(2) and fchmod(2) on
"/run/user/<UID>/pulse" which is currently blocked by the syscall
filter; this patch adds the two missing syscalls to the whitelist.
You can reproduce this problem with the following command:
# qemu -monitor stdio -device intel-hda -device hda-duplex
If watched under strace the following syscalls are shown:
mkdir("/run/user/0/pulse", 0700)
fchmod(11, 0700) [NOTE: 11 is the fd for /run/user/0/pulse]
