It's not clear to me why only the frontend has been tristate. Switch the
backend to be, too.

Actually although the frontend is a tristate, it cannot really work as a
module. Specifically see pvcalls_stream_ops in the enabling patch (still
not upstream):
https://github.com/lf-edge/runx/blob/master/kernel/patches/0001-patch-pvcalls_enable.patch
So I had to change tristate to bool for XEN_PVCALLS_FRONTEND in our
internal kernel tree.
That said, the PVCalls backend could very well be a module and
technically I don't see any reasons why not. So:
