rauc.inc: add config for pkcs11_engine

[gumulka]

Add a PACKAGECONFIG option to en-/disable pkcs11_engine named engine, because it disables engine support for openssl, not pkcs11 support. It is enabled by default to have no disruption to previous versions

@gumulka I find the commit message quite hard to read. Maybe split up the sentence or at least set "engine" into quotes.

With the openssl context left out, I find it hard to tell what engine refers to, thus maybe something like openssl-engine for the config name?

If I'm not mistaken, this disables engine support for native and nativesdk which does not align well with the commit message.

Maybe also add a short note about the use case for this option.

Thank you for splitting this up.

I'd assume you intend to stay with this naming since you didn't change it?

I can't find this comment addressed. Am I mistaken here?

You don't find this necessary I guess?

@gumulka Also please target the master branch for new features.
