[Openembedded-architecture] x11-common versus xserver-common

[Philip Balister]

I fell over this issue again today and inserted a:

VIRTUAL-RUNTIME_xserver_common = "xserver-common"

to get some consistency in a build.

Both of these files seem have the same purpose.

This problem falls into the bin of things that is seriously annoying and
very, very difficult to explain to people not intimately familiar with
OpenEmbedded. How do we make it clear which one to select, or better
yet, move to one solution that works without any mysterious tweaks.
