Server platform works on OS X too

I remember some talk about removing the server platform, and just replacing it with a server=yes option when compiling... #11389

That said, I don't have a problem with this PR, despite that talk.

Maybe we should make the binary name more explicit to show whether it was compiled for Linux/*BSD ("X11", even though it's not using X11) or OSX? Maybe godot_server.x11.* and godot_server.osx.*?

(This will all be further refined when we split OS and Display and rename the X11 platform to Freedesktop, so it's not too bad if we abuse the "x11" identifier now IMO).

Sounds good to me, I'll add that change.
