compositor: add option to specify a weston.ini

Browse source 
Add a command line option to specify a file to be read instead of
weston.ini.

IVI-shell testing will at least temporarily need to specify a config
file, because it cannot run without. That is why this is being added,
but should be convenient for everybody, too.
