util: Fix mask for 172.16.0.0 private address range

Browse Source 
https://bugzilla.redhat.com/show_bug.cgi?id=905708

Only the first 12 bits should be set in the mask for this range. All
addresses between 172.16.0.0 and 172.31.255.255 are private.
(cherry picked from commit 6405713f2ab9243db7d856914aaefbd4f9747daa)
