[oe] [meta-handheld][PATCH] udev: generalize the check in touchscreen rule

[Andrea Adami]

* The rule only works for devices reporting ts pressure
* and ignores the other touchscreens (happens e.g. on ipaq h1940).
* a0,1,*18   a = absolute axes (ABS_X 0x00 ABS_Y 0x01 ABS_PRESSURE 0x18)
* (see include/linux/input.h)
*
* Guidelines for touchscreen suggest only ABS_X and ABS_Y are mandatory
* (http://kernel.org/doc/Documentation/input/event-codes.txt)
*
* Side-effect of the patch is to remove a dependency on meta-oe
* but using older udev from oe-core.
