Closes all the file descriptors previously passed to the object with
g_subprocess_launcher_take_fd(), g_subprocess_launcher_take_stderr_fd(), etc.
After calling this method, any subsequent calls to g_subprocess_launcher_spawn() or g_subprocess_launcher_spawnv() will
return %G_IO_ERROR_CLOSED. This method is idempotent if
called more than once.
This function is called automatically when the #GSubprocessLauncher
is disposed, but is provided separately so that garbage collected
language bindings can call it earlier to guarantee when FDs are closed.
