Disable C4090 in libisccfg

The MSVC detects mismatch of const qualifiers in cfg_map_{first,next}clause
functions just in BIND 9.11.  As this is harmless in this particular
case, just disable the warning for these two functions.

The warnings reported:

  lib\isccfg\parser.c(2160): warning C4090: '=': different 'const' qualifiers
  lib\isccfg\parser.c(2184): warning C4090: '=': different 'const' qualifiers
