Sergio Pastor Pérez cf2a11b966 derivations: Let ‘map-derivation’ correctly handle directories. ...

The 'map-derivation' procedure was trying to process directories as files.
When a derivation had a 'module import' directory as input, it threw an
exception since it tried to open it as a file.

* guix/derivations.scm (map-derivation): In ‘sources’, add
‘file-is-directory?’ case.
* tests/derivations.scm ("map-derivation, modules"): New test.
