[Buildroot] [PATCH v4] Patch file clarification & Co

[Luca Ceresoli]

Hi,

several Buildroot users reportedly asked details about how the patches
bundled with Buildroot are licensed.

Following the discussion during the latest Buildroot Developer Days, a
clarification has already been applied to COPYING.

The present patch adds the same clarification to the manual.

I removed the last patch of v2 ("legal-info: explicitly state how
patches are licensed"): it will only makes sense after Yann's
improvements to save the patches in legal-info will be applied. When
this happens, I'll take care to resend it.
