[BUG] No way to call spawn_async with envp = NULL

[andy128k]

Bug description

glib::spawn_async takes a slice for envp parameter. When it is called with empty slice it passes non-null pointer to g_spawn_async.

But g_spawn_async treats differently cases when env is empty and when it is null.

This is basically the same as gtk-rs/gir#1133 (which has a WIP PR). The way forward here for now would be to manually implement this function correctly until that PR is done.

@bilelmoussaoui what was the status with that PR?

I won't have the time to finish it, maybe in few months
