Log Message:
py-notify-python: remove package (EOL)

This package (in this incarnation) has been dead upstream since 2008,
and there are no longer any packages in pkgsrc that depend on it.
(There is a newer Python "notify2" upstream that replaces this, and
works with Python 3.x, but this isn't in pkgsrc proper at present,
though it is in pkgsrc-wip.)
