dracut-kdump: Use the first filtered ip address as dump directory

Browse Source 
For now, Kdump will use ipv4 address as dump directory, and it works, if
ipv4 is enabled.

Once Kdump start to support ipv6 protocol, we may only setup the ipv6
address exclusively. Modify the code to make Kdump work in either ipv4
and ipv6 protocol.
