qt4-embedded: avoid circular dependencies for reciped providing qt4-embedded

* qt4e.bbclass did add a dependency on qt4-embedded for recipes
  providing qt4-embedded. This breaks building of qt4-embedded-gles
  in 2 ways:

  1. PREFERRED_PROVIDER_qt4-embedded = qt4-embedded-gles
     adds a circular dependency.

  2. bitbake qt4-embedded-gles
     first builds and installs qt4-embedded to sysroots/ and then
     fails to link the qt4-embedded-gles build against the libs in
     sysroots which don't provide the gl specific symbols

* The fix avoids adding the dependency for package names _beginning_
  with 'qt4-embedded' (as it is done in the x11 version).
