channels: Address test failure.

Fixes <https://bugs.gnu.org/43940>.
Reported by Maxim Cournoyer <maxim.cournoyer@gmail.com>.

The "channel-instances->manifest" test would fail since
1d4ab335b22a93e01c2eb1eb3e93fc6534157040: 'quiet-guile' would be passed #f
as GUILE, and thus 'package-version' would fail with wrong-type-arg.

* guix/channels.scm (whole-package-for-legacy): Pass #:guile to
'whole-package'.
* tests/channels.scm ("channel-instances->manifest"): Remove 'test-expect-fail'.
