qtbase: add option to enable tslib support

- the tslib support is not enabled by default and configure doesn't have any option
to active it, so add the option to the build system,
- patch tslib support to get the device from the environment variable
(patch taken from https://github.com/prabindh/qt-configs/blob/master/qt5_1.0_Feb13/tslib.patch
- provide variable to enable tslib support in a bbappend (disabled by default)
- tested on an i.MX5x target with qt 5.0.2

TODO : test with 5.0, 5.0.1 and _git
