[liblo] [PATCH] Fix char type sending for big endian machines

Steve, sorry for for finding another issue so soon! It never rains,
and then it floods...

testlo fails on big endian machines with:
FAILED types[9] == 'c' && argv[9]->c == 'X' at testlo.c:578

Some debugging showed that:
argv[9]->c = ''
argv[9]->i = 88
Root cause of this lo_message_add_char(), which does an implicit
cast to an int.
The patch below removes this cast. With it testlo runs without errors
on machines of any endianness.

I have not tried sending messages between machines with different
endian types yet, but will probably get round to that soon.
