ncsid: Use PACKET_MR_PROMISC

Using IFF_PROMISC is dangerous because it requires us to set the IF
flag. The if flags cannot be set atomically, and they are expected to be
owned and managed by systemd-networkd. NCSId will sometimes race with
systemd-networkd and discard the IFF_UP flag and prevent the interface
from coming up during boot.

PACKET_MR_PROMISC does not depend on the flags and will not conflict
with other processes using the interface.
