[Xinglu Chen <public@yoctocell.xyz>]

This lets the user to only check for updates for packages installed in the
current profile.

If the user is using the imperative way to install packages, or uses
multiple manifests, this is a quick way to check for updates for the
installed packages.

* guix/scripts/refresh.scm (%options): Add '--installed' option.
* guix.texi (Invoking guix refresh): Document it.
