Report already broken packages as a separate category

[frenzymadness]

Fixes: #2

The new report looks like this:

fedora_revdep_check.py python-setuptools 80.10.2
These packages already FTBFS (not a new problem):
  python-colcon-core: python3-setuptools < 80
  python-zc-lockfile: python3dist(setuptools) = 78.1.1
  python-zope-testing: python3dist(setuptools) = 78.1.1

These packages already FTI (not a new problem):
  python3-colcon-core-0.20.1-1.fc44: python3.14dist(setuptools) < 80~~

It works. The new code makes sense. I did not check all the added test code.
