    Update Emscripten extension fork modules.md
    
    This just updates the URL to my fork, which is an up to date and mantained version.

premake5 generated compile command:

clang   -MD -MP -D_GLIBCXX_USE_CXX11_ABI=0 -DLUA_COMPAT_5_1 -DLUA_COMPAT_5_2 -DLUA_COMPAT_5_3  -O2 -g -Wall -Werror -Wno-strict-aliasing  -o "obj/release64/lullbc_luaexec/lua.o" -MF "obj/release64/lullbc_luaexec/lua.d" -c "../../wrap/lullbc/lua/lua.c"

additional info

If compile c++ file, will auto add -Wl,-rpath,@loader_path/. compile option when dll or exec generate

You can try adding this to https://github.com/premake/premake-core/blob/master/premake5.lua#L197 :

    runpathdirs { "." }

Thanks，runpathdirs is a good idea!

I try to fix this bug using below methods:

-- method 1:
filter { "system:macosx" }
    linkoptions { "-Wl,-rpath,@loader_path" }
filter {}

-- method 2(a mre elegant method):
filter { "system:macosx" }
    runpathdirs { "@loader_path" }
filter {}

I think this is a premake tool bug, I hope premake's developers can fix it

Unfortunately, I don't have an apple device to verify a build. If someone would put forward a PR with tests, I'd happily review it.
