Reported by Andreas Enge <andreas@enge.fr>.
* guix/diagnostics.scm (absolute-location): Return FILE from
'canonicalize-path' when 'search-path' fails.
* guix/packages.scm (package-field-location): New procedure 'file-name' and
use it. When 'search-path' does not find FILE in %LOAD-PATH, try
'canonicalize-path'.
* guix/upstream.scm (update-package-source): When 'search-path' fails, test if
FILE exists.
