Lua: Use Redis solaris compatability for cjson too
Lua: Use Redis solaris compatability for cjson too

cjson calls isinf, but some Solaris versions don't have isinf
even with the attempted fix we have in deps/Makefile.

We can harmlessly include the Redis solarisfixes.h header to
give cjson proper isinf.

Note: cjson has a compile-time setting for using their own defined
isinf, but the Redis definition in solarisfixes.h is more complete.

Fixes antirez#1620
