libpayload: Introduce new Kconfig to explicitly allow GPL code

There have been leaks of GPL code into libpayload for a while now, for
    new features or improvements that require third party code with no
    adequate alternative among BSD-licensed software. It seems silly and
    counter-productive to keep holding back features and performance
    improvements from libpayload for a use-case (proprietary payloads) that
    doesn't even seem to be implemented anywhere to date. Open-source
    payloads should not need to suffer to appease commercial ones.

Instead, this patch introduces a new Kconfig option to explicitly allow
    inclusion of GPL code. It will use Kconfig dependencies and/or Makefile
    rules to ensure that no GPL code can end up in the final payload if that
    option is unset, allowing proprietary payloads to keep working with the
    existing BSD-licensed feature set. New features and patches (that are
    sufficiently separate and self-contained to allow guarding through this
    config option) can choose whether to import GPL code, and need to depend
    on this option if they do.

Also clean up all (known) existing uses of GPL code to depend on the new
    option, add some recent third-party imports to the LICENSES file, and
    relicense the selfboot.c files to BSD with permission of the author.

    TEST=Compiled Falco and Nyan_Big both with and without the new option,
    disassembled output binaries to ensure that memcpy() looks as expected.
