ENGINE_pkcs11 should be configured to load p11-kit-proxy.so as its
default provider module.

Any third party PKCS#11 module you want to use should be configured in
p11-kit properly, and it'll then be available to well-behaved
applications. Including sign-file.

You should need any of the special OpenSSL config horridness.
