home: import: Fix handling of manifest entries with specific output.

specification->package fails on manifest entries with specific outputs,
resulting in an invalid home configuration.  This changes the import command
to use specification->package+output instead.

* guix/scripts/home/import.scm (manifest+configuration-files->code): Make sure
manifest entries with specific output are also handled.
* tests/home-import.scm: Specify output in home environment manifest entry.
