Adds a general wlsc_compositor_shutdown() function that all output
backends call when shutting down. wlsc_compositor_shutdown() will call
a new 'destroy' method of each output to perform backend-specific
cleanup (e.g., turning off the hardware cursor in the DRM compositor).

I may have missed something, but - since the Wayland compositor
already picks a platform backend, opens a connection and initializes the
backend specific display data structure it doesn't make sense
to let egl pick a platform. If it picks a different one the
display specific data structure will most likely not match.
Thus determine the platform in the Wayland rendering backend by setting
the EGL_PLATFORM env variable.
For the client any other platform than 'wayland' doesn't seem to make
sense.
I'm not sure if I've got the the platform ofr openfwd right.
