nwfilter: Do not require DHCP requests to be broadcasted

Browse Source 
Remove the requirement that DHCP messages have to be broadcasted.
DHCP requests are most often sent via broadcast but can be directed
towards a specific DHCP server. For example 'dhclient' takes '-s <server>'
as a command line parameter thus allowing DHCP requests to be sent to a
specific DHCP server.
