[FIX] report: only set --viewport-size for some reports

viewport-size was add by 2254a97 (and changed by 0ea94b4) to force
wkhtmltopdf to use `col-md-*` bootstrap css classes. As this argument
change the `window` size and not the screen size, this lead to smaller
fonts and overflow issues in reports.
Only change it for reports that need it.

Closes #7882
