Don't abort upon untracked TouchUpdate events

Emacs might get an untracked TouchUpdate event in the unlikely
event of a device hierarchy change during a touch sequence, in
which case all devices and touchpoints will be reset.

* src/xterm.c (handle_one_xevent): Don't abort when receiving
a TouchUpdate that isn't part of a touch sequence.
