[bug#44663] [PATCH] ui: Launch $PAGER through the shell.

[Tobias Geerinckx-Rice via Guix-patches via <guix-patches@gnu.org>]

This is the convention elsewhere and sounds like the right thing to do.

* guix/ui.scm (call-with-paginated-output-port): Substitute OPEN-PIPE
for OPEN-PIPE*.

Reported by Daniel Brooks <db48x@db48x.net>.
