rpi: prevent segfault on shut-down due to NULL backend

Browse source 
When running with the RPi backend, Weston sefaults during shutdown. This is
due to the fact that `compositor->backend` is never initialised, and there
is no NULL check prior to calling `destroy()`.

This commit fixes the issue by making `rpi_backend_create()` intialise
`compositor->backend` - just like the X11 backend does.
