[PATCH v3] configure.ac: fix code misplacing for KDRIVE_{KBD, MOUSE, EVDEV} auto-detection

[Laércio de Sousa]

KDrive input drivers "kbd", "mouse", and "evdev" should be automatically built
for linux systems. However, due to a code misplacing in configure.ac, the
auto-detection test is being performed AFTER the corresponding AC_DEFINEs' calls,
so that the drivers are NOT being built, regardless the test result.

This bug should be affecting previous xorg-server releases. Please consider
backporting this patch to all maintained ones!
