problem with net-mgmt/icinga2 upgrading from 2.4.10 to 2.5.1 (r420729)

[Walter Schwarzenfeld]

Cause I  only had a quick look  in  it, I have not configured it,
but
if I remove USESßssl
It seems to start (So I have eror messages, but it seems they are only  
of missing cofiguration). Please, test it.
