libnss-mdns: avoid race condition in postinst
Writing to "/tmp/nsswitch.conf" leads to a race condition if two copies of the postinst are running simultaneously. Fix this by modifying /etc/nsswitch.conf in place using sed -i. Also make the same change to the prerm for consistency although the race will not occur here in practice.
