iOS arm64 Fails Compiling due to reliance on 'system' (depricated)

[jet082]

As it says in the title.

The error is as follows:

cc -arch arm64 -marm -miphoneos-version-min=8.0 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.4.sdk -O2 -Wall -fPIC -O3 -w -g -fPIC -I/usr/local/opt/icu4c/include  -c -o lstrlib.o lstrlib.c

         ^

This is related to this bug: alibaba/LuaViewSDK#84

It would appear 'system' is not available in XCode 9+

Commenting out the line

lua_pushinteger(L, system(luaL_optstring(L, 1, NULL)));

in deps/lua/src/loslib.c as suggested in that issue linked above seems to fix the problem.

I have confirmed the above changes allow the code to compile and I have tested some sample content and it runs on iOS-arm64.
