CP5022{0,1,2}: convert characters in ku 0x2D (13th row) correctly

Essentially, CP5022{0,1,2} are to CP932 as ISO-2022-JP is to Shift-JIS.
As Shift-JIS and ISO-2022-JP both encode characters from the JIS X 0208 charset,
CP932 and CP5022x both encode characters from JIS X 0208 _plus_ extra characters
added as MicroSoft vendor extensions.

Among the added characters are a number of symbols which MS put in the 13th row
of the 94x94 character table. (In JIS X 0208, that row is empty.)

mbfilter_cp50220x.c had an `if` clause which was intended to handle the
conversion of characters in that 13th row, but it was dead code, as the previous
clause was always true in those cases. The solution is to reverse the order of
those two clauses (just as they already appeared in mbfilter_cp932.c).
