[PATCH v10 6/8] dracut-module-setup: Support the static ip with ipv6 mode

In order to enhance kdump to support ipv6, support the static ip with ipv6, which ipv4 has supported already. Due to the different format with ipv4 and ipv6, dracut uses bracket"[]" to quote the ipv6 address to identify it in the 2nd kernel.
