libssh2 with rsa-sha2-256, rsa-sha2-512

[João M. S. Silva]

Hi,
Having been able to fix the issue with a recent checkout from git I now
face the problem of how to deliver it to the OS.

help needed?
I'm trying to avoid installing the built version directly into /usr/local.
Instead, having a .deb would be cleaner.
Thanks.
