main: Add some command line argument conflicts

Browse Source 
Add explicit exclusions with --net-backend from --block-backend (and
vice-versa.) And also with "--kernel" as this is the option for "VM boot" that is never optional.

Ideally we would conflcit the backend arguments against the "vm-group"
however this does not work as it includes some arguments that have a
default value set and thus clap thinks those arguments are always
provided. Conflicting with "--kernel" is thus a reasonable compromise.
