[PATCH] configure: fix up check for tslib.

[Peter Hutterer]

Reduce the tslib-check to the pkg-config check only instead of the previous
library symbol check followd by a pkg-config check.

This patch also reduces the required version of tslib back down to
tslib-0.0. Unfortunately, the 1.0 tarball available through
http://tslib.berlios.de/ still announces itself as 0.0.2.
