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.

+Subject: [PATCH] Add configuration option for no input device.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+[Backported from master, 75b7197.]
+
+As it has been discussed in the past [1], running Weston
+without any input device at launch might be beneficial for
+some use cases.
+
+Certainly, it's best for the vast majority of users (and
+the project) to require an input device to be present, as
+to avoid frustration and hassle, but for those brave souls
+that so prefer, this patch lets them run without any input
+device at all.
+
+This introduces a simple configuration in weston.ini:
+  [core]
+  require-input=true
+
+True is the default, so no behavioral change is introduced.
