Split out wayland-doc subpackage for documentation

Instead of using a confusingly named 'wayland' subpackage just for
shipping development documentation, put it in 'wayland-doc' and drop the
'wayland' subpackage.

As a side effect, this also fixes the build on F24 with rpm 4.12.90
which would otherwise fail with:

RPM build errors:

   /usr/share/doc/wayland/Wayland/en-US/html/apa.html
