virtualkeyboard does not work with lipi_toolkit enabled

lipi_toolkit feature is currently broken in 5.7 branch. There are number of compilation fixes in 5.6 branch that have not been merged to 5.7. Also commit with Change-Id: I2f983cb8fc3713fea25cd103013d0ce5356ffa0c broke lipi_toolkit at runtime, since the engine libraries and configs are not in expected locations.
