This can probably be solved by using GioUnix.InputStream instead of Gio.UnixInputStream, like here.

From gnome-shell MR:

GLib 2.79.2 split out the platform specific Gio APIs into a separate
GIRs, while still keeping a copy in the Gio GIR. gjs then added warnings
about the APIs being moved.

This bumps the Gio(Unix) version requirement to 2.79.2 and switches to
using the new GioUnix GIR.

See: GNOME/glib!3892
See: GNOME/gjs!918
Closes: GNOME/gnome-shell#7539

Glancing over GNOME/glib!3892, the rationale for introducing the breaking change in Glib was supporting Windows. YUCK.

This warning is ugly but (up to now at least) non-fatal.
