[Bug 1897117] [NEW] liblasso3 on Bionic fails to process the ECP authn response

[Ionut-Madalin Balutoiu]

Public bug reported:

The liblasso3 package (dependency of libapache2-mod-auth-mellon) fails
when processing a ECP authn response.

Error message given by the Apache2 Mellon auth module:
[auth_mellon:error] Error processing ECP authn response. Lasso error: [101] Signature element not found.

This issue can be reproduced into an OpenStack environment with Keystone
to Keystone federation, using Apache2 Mellon module for the SP (service
provider).

I managed to reproduce this on:
* Ubuntu 18.04 (Bionic) with liblasso3 2.5.1-0ubuntu1.1
* Ubuntu 20.04 (Focal) with liblasso3 2.6.0-7ubuntu1

This was fixed in the upstream Lasso project
(https://dev.entrouvert.org/issues/26828), and it is shipped with
versions 2.6.1 or newer.

I tested liblasso3 2.6.1 on both Bionic and Focal and it fixes the
problem.
