[Buildroot] [PATCH 02/10] add openssl as a dependency to certain packages

[Adam Duskett]

The following packages only work with OpenSSL.  In anticipation for the next
patch, these packages must explicitly rely on OpenSSL in thier Config.in
files.

The reason for each package is as follows:

luvi:
  Uses TS_RESP_CTX_set_time_cb which is removed from LibreSSL.
  This is the only package that currently uses this API in
  BuildRoot.

nodejs:
  Bundles it's own OpenSSL variant, which is tightly intigrated
  with node.  There is a ongoing effort to make the SSL library
  agnostic.  Gentoo has provided a patch to make NodeJS work with
  LibreSSL, but I haven't been able to test it.

python-cryptography:
  Newer versions compile against LibreSSL, however there
  are some issues running the latest version when
  cross compiling.

rauc:
   Rauc uses smc exclusively, which LibreSSL does not support.

stunnel:
  The author of stunnel has on two occasions said he will now
  allow Stunnel to be compiled against LibreSSL.
