[morty] weston: Add no-input-device patch to 1.11.0.

The included patch, backported from Weston master (and OE-Core
master since Weston 1.11.1, b6864b1), allows it to run without
any input device at launch. An ini option is introduced for
this purpose, so there is no behavioral change.

Related change in weston.ini:
  [core]
  require-input=true

Default is true; setting it false allows Weston to run
without a keyboard or mouse, which is handy for automated
environments.
