e-wm: use illume2 instead of illume1, fix illume-keyboard paths and locales packaging

* illume2 and illume1 shouldn't be compiled both anymore
  http://trac.enlightenment.org/e/changeset/50884
  keep only illume2 as it's preferred by upstream
* separate illume2 (illume-home) to new package e-wm-config-illume2 and
  make it default
* remove illume-keyboard-default_svn.bb recipe and create illume
  keyboard packages from e-wm build directly (otherwise installed twice)
* update KEYBOARD_DIR in illume-keyboards-shr
* don't include all locales in FILES_${PN}
