bugreport/bugreportz: improve help/errors.
Fix bugreportz to report the usage error rather than ignore extra
arguments. Also fix the synopsis in the usage text to include -p.
Update the bugreport warnings to have the correct way to use bugreportz,
since we now know it doesn't actually take a filename and instead
chooses its own.
