wireprotov2: always advertise raw repo requirements

I'm pretty sure my original thinking behind making it conditional
on stream clone support was that the behavior mirrored wire protocol
version 1.

I don't see a compelling reason for us to not advertise the server's
storage requirements. The proper way to advertise stream clone support
in wireprotov2 would be to not advertise the command(s) required to
perform stream clone or to advertise a separate capability denoting
stream clone support.

Stream clone isn't yet implemented on wireprotov2, so we can cross
this bridge later.
