In makedef.pl, remove duplicate symbols passed to try_symbols() for OS/2.

Code to try the 4 thread-specific symbols was added in 2003 by commit
5c728af092d5feba. However, all 4 symbols were already listed in makedef.pl,
added in 1999 by commit 3cfae81b38bc8edd.

(Unlike other platforms, on OS/2 adding symbols to %export that aren't
actually compiled in does not cause errors, as there is code later in
makedef.pl to read in miniperl.map, and strip from %export all symbols not
listed there.)
