[gvfs] If there are no mtimes in the file, use 0 as mtime base

    If there are no mtimes in the file, use 0 as mtime base
    
    Before we used to store -1 (0xffffffff) as the mtime base in this case.
    This value is not used if there are no mtimes though, so this is more
    like a cosmetic change.
