Subject: weston-init: customize

For upstream weston (i.e. not the imx fork) the following two settings
are missing in the default weston.ini. Add them.

- Set idle-time=0 to prevent weston from entering a screensaver mode
  on idle.
- Set use-pixman=true for modules without a GPU to prevent weston
  from using a CPU to nearly 100% and having a very slow screen update
  rate, e.g. a not smoothly moving cursor.

(downstream already has idle-time=0 set and performs well without
use-pixman=true)
