Don't call pixman_disable_out_of_bounds_workaround() anymore

Pixman used to have a workaround for a bug in old X servers, and this
function was used to disable that workaround in servers known to be
fixed.

Since 0.22, which the X server depends on, the workaround doesn't
exist anymore, so there is no point disabling it.
