efl: update svn recipes to use 1.7 branch

* E17 will depend only on EFL 1.7 (probably 1.7.2)
* next EFL release we'll have to update recipes a lot to use unified EFL
  source tree, maybe also git instead of svn
* some libs are for newer EFL_SRCREV moved to IN-EFL subdirectory in
  trunk (eet  eina  embryo  eo  evas  evil)
* trunk depends on edbus2 (edbus dir instead of e_dbus)
