    desktop: fix the appstream unit tests.
    
    The first validation command was actually failing but the test was not,
    because only the last return value is taken into account, obviously. Add
    a '&&' between the commands.
    Also test against the built files, not the templates (in particular
    because `appstream-util` doesn't like .in.in templates, and anyway it's
    always better to test against the finale file).
    Finally move to "validate-relax" test for the time being.
    "validate-strict" actually makes a bunch of errors, but I can't make the
    time to look at these now. Let's just settle with basic validation at
    least.
