Joel Cunningham 1147b9ce38 test_dhcp: set link up on net_test netif
DHCP test code didn't set link up on net_test netif (exposed by changes
in 637bce91b45c855964f549f91bc41a32317eac4c)

Then during the test_dhcp function, a Gratuitous ARP was not sent during
the call to dhcp_bind() because the link was still down

The sets the link state for all DHCP test functions
