gstdio: Temporarily disable g_close() warning on macOS
It causes the tests to fail, which suggests some latent FD handling bug on macOS (but not other platforms).
Unfortunately I’m unable to debug that due to not having access to a macOS machine, and it’s blocking CI for the rest of the project.
So disable it on macOS for now, until someone with access to a macOS machine can take a look.
