arith: Fix variables 'nan' and 'inf' in arithmetic for POSIX mode

Browse source 
The --posix compliance option now disables the case-insensitive
special floating point constants Inf and NaN so that all case
variants of $((inf)) and $((nan)) refer to the variables by those
names as the standard requires. (BUG_ARITHNAN)

src/cmd/ksh93/sh/arith.c: arith():
- Only do case-insensitive checks for "Inf" and "NaN" if the POSIX
  option is off.
