umdns: add missing syscalls to seccomp filter
Looks like 'openat', 'pipe2' and 'ppoll' are now needed, possibly due
to changes on libraries used by umdns now using slightly different
calls.
Found using
/etc/init.d/umdns trace
now use umdns, ie. cover all ubus call etc., then
/etc/init.d/umdns stop
find list of syscalls traced in /tmp/umdns.*.json
Fixes: FS#3355 ("UMDNS: does not start on master with seccomp")

(cherry picked from commit 00a85a163405fdf9bee4d8c3f0ee87ca9ed259d6)
