Subject: gnu: mutter: Update to 3.22.2.

* gnu/packages/gnome.scm (mutter): Update to 3.22.2.  Add comment
noting that forked versions of 'cogl' and 'clutter' are now bundled
with mutter.
[arguments]: Add "--disable-wayland" to configure flags.  Add TODO comments
reminding us to add support for wayland and the native backend.  Add configure
flags from 'cogl' and 'clutter'.
[propagated-inputs]: Remove clutter.  Add new inputs needed by
mutter-{clutter,cogl}-1.0.pc.
[inputs]: Add libgudev and libxrandr.  Move libxkbcommon to propagated-inputs.
Remove mesa-headers, replaced by mesa in propagated-inputs.
(cogl, clutter): Add comments to note that changes to cogl and clutter may
also be needed in mutter.
