<pre>With mesa 10.5.1 and on, weston won't start with DRM backend, saying that it
can't find EGL config. I looked into it a little, weston attempts to find
XRGB8888 but it only gets ARGB8888 and RGB565.
Reverting commit 65c8965d033cf9ade5e6f3c88bda6d247d46af9d: egl: Take alpha bits
into account when selecting GBM formats, which has been backported to 10.5 and
10.4 branches eliminates the problem.</pre>
