guix build, archive, graph: Disable absolute file port name canonicalization.
This avoids an 'lstat' storm. Specifically:
./pre-inst-env strace -c guix build -nd libreoffice
goes from 1,711 to 214 'lstat' calls.
* guix/scripts/build.scm (options->things-to-build): When SPEC matches
'derivation-path?', call 'canonicalize-path'.
(guix-build): Remove 'with-fluids' for %FILE-PORT-NAME-CANONICALIZATION.
* guix/scripts/archive.scm (guix-archive): Remove 'with-fluids' for
%FILE-PORT-NAME-CANONICALIZATION.
* guix/scripts/graph.scm (guix-graph): Likewise.
