fw4: ensure that negative bitcounts are properly translated

Set bits to `-1` after converting a negative count into an inverted mask,
in order to ensure that the resulting subnet list is properly grouped
and rendered later on.

Also add some minimal test coverage for this case.

Fixes: #9764
Fixes: c22eeef ("fw4: support negative CIDR bit notation")
