gio: check the given child name is not an absolute path

Browse Source 
As this would have undesirable consequence.

Quoting Philip Withnall:
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/2305#note_1294729:

  The documentation never said anything about accepting absolute paths,
  so any code which is relying on that is relying on undocumented
  behaviour. We’re allowed to change that.
