netutils/dhcpd: specify port number when binding the socket

This commit is to patch for specifying port number of dhcp server when
binding the socket. If there is no port number specified, DHCP packets
have wrong port number and this may cause interoperability problems
during DHCP handshaking with various other platforms.
