cli: add install print-configuration --all

When `install print-configuration` is run some options (notably
the kargs) are currently filtered out. This makes sense because
in general `bootc install to-filesystem` takes care of them.

However with the recent work in image-builder/osbuild to use
bootc containers directly as inputs to build ISOs [0],[1]
we would like to get access to the kernel args too because
when constructing a bootable ISO we also want to add the
bootc container kargs.
