scripts: import: Increase column width for pretty-printer.

Browse Source 
Previously, the max column width for the pretty-printer was 50, which caused
generated package definitions to include unnecessary newlines, e.g.,

  (home-page
    "https://gitlab.com/ttyperacer/terminal-typeracer")

instead of

  (home-page "https://gitlab.com/ttyperacer/terminal-typeracer")

* guix/scripts/import.scm (guix-import): Set max expression width to 80 when
pretty-printing.
