provide kdumpctl get-default-crashkernel for kdump_anaconda_addon and RPM scriptlet

Browse Source 
Provide "kdumpctl get-default-crashkernel" for kdump_anaconda_addon
so crashkernel.default isn't needed.

When fadump is on, kdump_anaconda_addon would need to specify the dump
mode, i.e. "kdumpctl get-default-crashkernel fadump".

This interface would also be used by RPM scriptlet [1] to fetch default
crashkernel value.
