Subject: [PATCH] xfree86: Use last Screen section found to prefer xorg.conf

Allowing multiple .conf files with xorg.conf.d works well for InputClass
where any section in xorg.conf would override settings from previous
.conf files typically installed by the distro. This does not work well
with Screen sections where the first section found has been used when
the Layout doesn't specify a Screen. Instead, use the last Screen
section found to give preference to xorg.conf and match the InputScreen
semantics.
