    iconvdata/tst-table-charmap.sh: remove handling of old, borrowed format
    
    This "Old POSIX/DKUUG borrowed format" handling is original to the file
    and doesn't seem to have ever been used, i.e. id/t-t-c doesn't seem to
    have ever been called with argv[1] == POSIX.
    
    Upcoming is a POSIX charmap, which would inadvertently trigger this.
