[Buildroot] [PATCH 1/1] Adding the Scrypt key derivation library.

[Thomas Petazzoni]

Dear Parnell Springmeyer,

Thanks for your contribution!

You should normally send patches inline (using git send-email) rather
than as an attachment. This allows to more easily review your patch by
simply replying to your e-mail.

That being said, for this first patch, I applied it to our next branch,
after doing quite a few changes:

    [Thomas:
      - move from "Libraries -> Crypto" to "System tools", since it only
        installs one binary, scrypt, and no library.
      - bump from 1.1.6 to 1.2.0
      - add comment in the .hash file explaining where the hash is coming
        from.
      - add missing dependency on OpenSSL
      - use BSD-2c as the license code, instead of BSD2
      - use 'main.c' as the license file.]

I messed up a bit when committing, since I committed your original
patch, and then separately my changes. But at least this way you can
clearly see what I have changed:

Thanks!
