luasystem no longer compiles with luajit

[rgg-dtemple]

Hello,

Following LuaJIT/LuaJIT@cd8d0a4 luajit will no longer compile because it is missing the #include for limits.h. The below error is from an install of busted by luarocks using luajit version LuaJIT 2.1.1734355927

I haven't verified but I would suspect lifting https://github.com/lunarmodules/luasystem/blob/master/src/time.c#L11 out of the #ifdef should fix it
