ui: Initialize %FILE-PORT-NAME-CANONICALIZATION to #f. 

This avoids loads of needless 'stat' calls due to the default 'relative
setting and the 'canonicalize-path' calls it leads to.  This was
especially visible when 'guix substitute' access files in
/var/guix/substitute/cache.

* guix/ui.scm (run-guix-command): Set %FILE-PORT-NAME-CANONICALIZATION
to #f.
