Subject: [PATCH] net/9p/usbg: allow building as standalone module

There is no reason only the usbg transport would not be its own module,
so make it tristate.

In particular, this fixes a couple of issues the current bool had:
- trans_usbg was apparently not compiled at all when NET_9P=m
- the workaround added in commit 2193ede180dd ("net/9p/usbg: fix
CONFIG_USB_GADGET dependency") became redundant because a tristate item
cannot be built-in when its dependency is a module, so we can depend on
USB_GADGET "normally" again.
