Merge branch 'fs/ssh-signing-other-keytypes'

The cryptographic signing using ssh keys can specify literal keys
for keytypes whose name do not begin with the "ssh-" prefix by
using the "key::" prefix mechanism (e.g. "key::ecdsa-sha2-nistp256").

* fs/ssh-signing-other-keytypes:
  ssh signing: make sign/amend test more resilient
  ssh signing: support non ssh-* keytypes
