  ovs-save: Handle different 'ip addr show' output.

On RHEL 7.4 (with iproute-3.10.0-87), a DHCP provided
ipv4 address has the "dynamic" keyword set. For e.g
"ip addr show breth0 | grep inet" shows:

    inet 10.116.248.91/20 brd 10.116.255.255 scope global dynamic breth0
    inet6 fe80::250:56ff:fea8:fdf0/64 scope link

The keyword "dynamic" (according to 'man ip-address') is only
used for ipv6, but in this case this is not true. Our current
code will skip the ipv4 address restoration because of this.

With this commit, we special case "dynamic" keyword to be valid
in case of ipv4.
