Bug#933655: pychecker: Package is deprecated and will be removed - do not use

[Kenneth J. Pronovici]

Package: pychecker
Severity: serious
Justification: Policy 5.9.2

Pychecker depends on Python 2, and can't be converted to Python 3.  It has also
been unmaintained upstream for most of a decade.  I have filed bug #932575
requesting its removal.  Please do not rely on it as a runtime dependency or a
build dependency.
