meson: fix warnings for extract_all_objects function

The "recursive:" kwarg is available in the targeted minimum version of
meson, and is basically required if you want to not emit warnings and
maybe error with --fatal-meson-warnings.

There are two basic solutions to this problem:

- The current default behavior is false, so explicitly opt in to that
  value. None of these internal libraries use recursive objects anyway.

- Use link_with to link to the static library directly, rather than the
  extracted objects.

Option 2 is what used to be done before commit
62af03bda8, but it only works with meson
>=0.52 and previously had buggy behavior.

Since the minimum version of meson is now 0.52, it is safe to revert
that commit and go back to using link_with, and therefore option 2 is
chosen.
