Always report hit counts correctly, even if ignored using -m

This commit means that the output provides useful summary data,
even if the lower-level hits are suppressed.

Note that this does use a little more memory when some hits
are supressed, since the hitlist is fully created even
if only parts are displayed.  However, modern systems have
lots of memory. Hopefully we'll never analyze software
with so many problems that this is a problem itself :-).
If someone ever has that problem, they can output everything
and filter it separately.

 Not every hit is necessarily a security vulnerability.
