    glocalfile: Only check for .hidden files if standard::is-hidden is requested
    
    For OSTree, I use Gio and also really care about performance.  It's
    disturbing to see open('.hidden') all over my straces and such.  At
    the moment I have an explicit set of things to query, as opposed to
    "standard::*", since even before this that also implies an lstat() of
    the parent directory.
    
    This matches up with what we do for all the other attributes.
