[PATCH 2/2] Remove misleading BCP 78 boilerplate

[Nicholas D Steeves <nsteeves@gmail.com>]

BCP 78 applies to RFC 6234, but sha224-256.c is Simplified BSD.

This causes the following lintian error when building on Debian and
Debian derivatives:

    E: btrfs-progs source: license-problem-non-free-RFC-BCP78
       tests/sha224-256.c

Please consult the following email from debian-legal@lists.debian.org
