DaemonCompiler: do not omit main parameter name in C

Do not omit main parameter name in C.

Fixes #1505:

• Compiler detection is flaky and spews errors #1505

This produced those errors:

../../daemon/cmake/DaemonCompiler/DaemonCompiler.c:163:13: error: parameter name omitted
int main(int, char**) {
            ^
../../daemon/cmake/DaemonCompiler/DaemonCompiler.c:163:21: error: parameter name omitted
int main(int, char**) {
                    ^
7 warnings and 2 errors generated.

Actually my first implementation of parsing the output of cc -dM -E could not be subject to that (no compilation was involved at all).

Why not use the int main() no-arg variant? Then you can be sure not to get trolled by unused argument warnings.

I have no opinion on this. If it is preferred at some point we can do that too, but right now it works so let's consider it fine.

Also the int main(int argc, char** argv) variant is now used for years in the DæmonArchitecture code so let's stick to that for now.
