Merge patch series "rsa: Add rsa_verify_openssl() to use openssl for host builds"

Paul HENRYS <[email protected]> says:

This serie of patches adds a new tool to authenticate files signed with
a preload header.  This tool is also used in the tests to actually
verify the authenticity of the file signed with such a preload header.
