bitbake: server: Remove none server

The process server backend has been serving well as the default for a long
time now and the UI model is much better thought out that it used to be. With
the move to make bitbake a memory resident process, the none server is now
looking rather pointless and complicates the code needlessly. Lets therefore
now remove it.
