edit Falco license info so that GitHub recognizes it

[eirinikos]

Hello! 👋

(CCing @dankohn who has requested this work so that the license will appear correctly in https://landscape.cncf.io/selected=sysdig-falco)

(Please see the corresponding PR for the Sysdig repo: draios/sysdig#1104)

GitHub uses a library called Licensee to identify a project's license
type. It shows this information in the status bar and via the API if it
can unambiguously identify the license.

This commit updates the COPYING file so that it contains only the full
text of the GPL 2.0 license. The info that pertains to OpenSSL has now
been moved to the "License Terms" section in the README.

Collectively, these changes allow Licensee to successfully identify the
license type of Falco as GPL 2.0.

Thanks, I'm checking on our side if the changes are ok to make. (Pretty sure they will be, but just checking).

In the meantime, could you edit your commit so it contains falco-CLA-1.0-... lines as described here? https://github.com/draios/falco#what-do-i-need-to-do-in-order-to-contribute-code

Thanks for the note. In regards to the git commit sign-off, I'm not sure why my PR is failing the sign-off-checker.

I just double-checked my commit message to make sure that I remembered to include a sign-off. Is there something I'm missing?

[mstemm]

Hmm, you're right, and the text in the commit looks correct to me. Let me double-check the webhook on our side.

[mstemm]

Still trying to figure out what's up with the webhook, but in the meanwhile I'll go ahead and merge this.

Thanks a lot, @mstemm !
