[Buildroot] [PATCH] sg3_utils: improve license description

[Rahul Bedarkar <rahulbedarkar89@gmail.com>]

Library is licensed under BSD-3-Clause. Some programs are licensed
under GPL-2.0+ while other are BSD-3-Clause. Annotate licenses with
components and improve readability of license strings when
conditionally specifying license for programs using := instead of +=.
