Fix Weston crash on touchscreen input
Check for touch->focus before using it, as some touchscreens will generate
out-of-screen coordinates and cause touch->focus to be NULL. (e.g. Raspberry Pi
display, some displays after weston-calibrator)
Bug-AGL: SPEC-309
Upstream-Status: Backport [https://cgit.freedesktop.org/wayland/weston/commit/src/input.c?id=2c40d1d30eabe46706822a8b5c94579aeba58e84]
