Fixes <https://bugs.gnu.org/41214>.

* guix/quirks.scm (%bug-41214-patch): New variable.
(%patches): Add it.

Not restoring it would cause problems when running:

  guix time-machine --commit=6298c3ff

or similar because the target Guix would be built with 2.2, and then
we'd erroneously go on and attempt build the profile with 2.2.  This
would fail because profile dependencies such as "guile-gdbm-ffi" now
target 3.0.

* guix/channels.scm (call-with-guile): New procedure.
(with-guile): New macro.

just once.  This ensures that '%guile-for-build' is restored
afterwards.
