Test pkcs11 URI support for UEFI capsule generation. For
simplicity only private key is defined in binman section
as softhsm tool doesn't support certificate import (yet).

This seems brittle, isn't there a better mechanism than this that can be
offered by distros? For openssl, installing libengine-pkcs11-openssl
(and setting the provider in the OPENSSL_CONF env variable) was enough.
Is there something similar to that for gnutls?
I don't think this will work on arm64 hosts, c.f.

Don't you want to validate it's properly signed?
