Upstream forwarding test failure

[Dmitry Belyavskiy]

Dear colleagues,

I came across an upstream test suite failure on Fedora 36.
The test in question is forwarding, the output is

==========

==========

The test (especially built from upstream) shouldn't be affected by Fedora
cryptography limitations. Unfortunately I also can't get any clues from
regress/failed_ssh.log

Any help will be appreciated. Many thanks in advance!
