iconv: fix missing bounds checking for shift_jis decoding
the jis0208 table we use is only 84x94 in size, but the shift_jis
encoding supports a 94x94 grid. attempts to convert sequences outside
of the supported zone resulted in out-of-bounds table reads,
misinterpreting adjacent rodata as part of the character table and
thereby converting these sequences to unexpected characters.
