[Buildroot] [PATCH 1/3] weston: improve selection of compositor

[Arnout Vandecappelle (Essensium/Mind)]

The way the compositor was selected in Config.in was counter-intuitive,
because the fbdev backend is selected by default even if a different one
is available.

Instead, select the fbdev backend only if no other one was selected by
the user.

Also re-ordered the compositor options, putting fbdev last. This is more
natural when the user wants to select both backends: after selecting the
RPi backend, the fbdev is automatically unselected but the user can move
one line down to select it again.
