[PATCH libinput] configure.ac: set AC_CONFIG_AUX_DIR

[Peter Hutterer]

If not set, libtool will search directories up to ../.. for an install-sh and
then dump the aux files there. This caused a couple of problems with the xorg
release.sh script that now uses worktrees but is generally bad behaviour
because we can't guarantee that we're not inside some other repository.

Set AC_CONFIG_AUX_DIR to avoid this behavior.
