netconsole: do not depend on experimental
netconsole: do not depend on experimental

Nowadays, most distributions enable netconsole by default,
including RHEL, Fedora, Debian, Arch, Opensuse. And
we don't have any bug reports about it. So I think there
is no need to mark it as experimental any more.
