[ostree] main: Consistently use "opt_" as a prefix for option local variables

[Colin Walters <walters src gnome org>]

commit 7b056e3c5090c2020394d8d95789190b838a3ec0
Author: Colin Walters <walters verbum org>
Date:   Tue Jul 23 18:33:29 2013 -0400

    main: Consistently use "opt_" as a prefix for option local variables
    
    This makes it easier to find where we're using global state, which is
    useful when refactoring code into libostree.
