[PATCH] Fix arandr.

[Ricardo Wurmus]

Hi Guix,

arandr doesn’t work as it needs “xrandr” at runtime.  I tried to patch
the sources to replace the path to the “xrandr” binary with a full store
item path, but this wasn’t quite as pretty as I hoped as the arandr
sources don’t define the path once but directly assemble command line
strings in several places.  Propagating “xrandr” is the cleaner solution
in my opinion.

~~ Ricardo
