build: Don't export GResource-related symbols with newer GLib

Browse Source 
This makes the desired behaviour explicit, and matches the behaviour
seen with Meson, where "external : false" is the default.

Before GNOME/glib!1468, not passing --internal to the resource compiler
meant "no special export attribute, do what you would normally do",
so these symbols were not exported due to our global use of
-fvisibility=hidden.

However, since GNOME/glib!1468, not passing --internal to the resource
compiler results in the symbols being decorated with G_MODULE_EXPORT,
which overrides -fvisibility=hidden. This was necessary because Windows
DLLs normally behave a bit like the equivalent of ELF libraries with
-fvisibility=hidden.
