Protectli bootsplash setting should be done within the buildsystem, not cbfstool post-build

Brief summary

Currently we build Protectli images with an empty black pixel image, then we substitute it in one partition with the actual logo using cbfstool.

The problem is that we do it as a "hotfix" after the build has finished, within build.sh. That doesn't work automatically in dasharo/dasharo, it requires an additional flag to do the logo swap and obtain a proper binary, which can easily result in incomplete binaries being delivered to the client.

We should instead do it all within the coreboot buildsystem, for the sake of simplicity.

The customizable logo is our own invention and we should know ourselves how to handle it. coreboot build system isn;t the right place for our every customization.

The dasharo/dasharo has an option to customize the logo. Just add PERSISTENT_LOGO and done...
