guix: Refactor script.
* scripts/guix.in: Remove empty surrounding ‘let’. Define 'main' as the procedure called when running the script. (maybe-augment-load-paths!): Rename to ... (augment-load-paths!): ... this. Use 'and=>' for 'file-exists?'. (run-guix-main): Rename to ... (main): ... this. Call 'augment-load-paths!'. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
