When the fetchmailconf port was split off from fetchmail, it inherited
some python version detection logic that had been intended to let
fetchmail be installed with or without python and work either way.
However, this logic 1) no longer works with current python packaging,
and 2) doesn't really make sense in the context of a 'fetchmailconf'
port that already depends on python.
This patch simplifies out that logic.
