Subject: [PATCH] guix: gexp: canonicalize file paths for import

From: Ryan Sundberg <[email-masked]>
Date: Mon, 17 Feb 2025 13:58:44 -0800

When we intern a file from the store during `imported-modules`, if the
file is a symlink (e.g., from a Guix profile), a dangling symlink can be
created in the module-import builder.

Follow any symlinks before interning the files to the store, so that the
file itself is imported and not the dangling link.
