testgetifaddr.sh: Always use the first IP addr from 'ip -4 addr' 

Terminate the awk after getting the first interface name and IP address
from 'ip -4 addr' output.  Otherwise, the test fails if the interface
in question has multiple IP addresses, as the test program returns
the first address, while awk prints all.
