support/scripts/pkg-stats: add linebreak opportunity in CPE ID

This adds an optional linebreak at the vendor attribute in the CPE ID.

It should be noted this is purely for formatting/layout purposes
and does not actually insert any additional characters
(newline or otherwise) into the rendered text.

This means that even though the text renders across two lines,
copy-pasting will still yield one line of text.
