Remove obsolte devicekit checks

Device kit support was removed, but the configure.ac checks were
left in place. A number of the XXX_REQUIRED=X.Y.Z variables were
not declared in the correct location (ie top of the file)

* configure.in: Remove device kit checks & move mis-placed variables
  to correct location
