Fix three clr2def2 character maps

The localedef(1) tool does not allow two symbols to be mapped to
the same unicode character.  I actually don't know if this is really
"wrong", but I had to adjust a couple of character sets that
violated this rule: ARMSCII-8 and Big5HKSCS.  Neither are present
on Illumos so that may explain why localedef(1) wasn't prepared
to do anything except throw an error.

The CP866 charset had a trailing garbage at the end of the file that
localedef didn't like, so I removed it.
