cbfstool: correct size left calculation for "empty" entries

After removing a file sandwiched between two other files, that file
    could no longer be re-added at the same location. cbfstool tried to
    add the file, and a new "empty" entry, which, together, would no
    longer fit, so it continued checking for the next available space.

Change the behavior to add the file if there is enough space for the
    file alone, then only add the "empty" entry if there is enough space
    for it.
