[bug#55081] [PATCH v2] Allow Guix root-dir overrides when working via Tramp.

[Brian Cully via Guix-patches via <guix-patches@gnu.org>]

From: Brian Cully <bjc@kublai.com>

Add only the local part of the root directory to the guile search
path. This lets you use Tramp to hack on a remote Guix checkout.

I think my last patch was mangled by GNUS, so I'm resending it.

FWIW, I've been using this for months without issue.
