build: Install .go files to $libdir/guile/X.Y.

* configure.ac: Define and substitute 'guileobjectdir'.
* Makefile.am (nobase_nodist_guilemodule_DATA): Remove $(GOBJECTS).
(nobase_nodist_guileobject_DATA): New variable.
(guix_install_go_files): Adjust accordingly.
(install-data-hook): Likewise.
* scripts/guix.in (config-lookup): Add 'exec_prefix' and
'guileobjectdir'.  Add '_' in VAR-REF-REGEXP.
(maybe-augment-load-paths!): Distinguish OBJECT-DIR from MODULE-DIR.
