libconnman-qt: update to 1.0.46, add recipe for qte

* Use _git version suffix, because it really is a Git recipe.
* Create an inc file to be shared between qt4x11 and qt4e.
* Use CONFIG+=notests, because CONFIG+=notest has no effect now.
* Reorder some variables according to style guide.
* Remove unneeded PROVIDES for ${PN}-plugin, which is already listed
  in PACKAGES.
* Hardcode branch to master, because no other branch exists upstream.
* Simplify do_install.
* Don't overwrite EXTRA_QMAKEVARS_PRE, because qt4e.bbclass uses
  it to pass on QT_LIBINFX.
* Generalize QT_IMPORTS_DIR to make it valid for qte.
