iwd: Don't add connection.interface-name by default

This setting can't be handled IWD (e.g. during autoactivations performed
by IWD) and although for manual activations NM will probably check it,
there's no reason for the IWD backend to restrict new profiles to one
interface plus when running IWD the udev permanent interface naming is
likely to be broken.
