I started that way, but seems we'd need additional changes when building
pflash to find the libstb/container.h, and since this new option is 
intended
to be used by users and not built into any code, this generic option is
probably ok for now.
If there are more features related to secure boot that we need to add to
pflash or requests from people we can revisit then.
