derivations: Raise an error when a module file is not found.
Suggested by Jookia. * guix/derivations.scm (&file-search-error): New error condition. (search-path*): Raise it when 'search-path' returns #f. * guix/gexp.scm (search-path*): Remove. * guix/ui.scm (call-with-error-handling): Add case for 'file-search-error?'. * tests/derivations.scm ("build-expression->derivation and invalid module name"): New test.
