OpenSSL: forward to BoringSSL.

This change will sit in the OpenSSL deps repo. When we switch to BoringSSL,
that patch will update DEPS to point to this revision. This avoids having to
update webrtc and libjingle repos at the same time.

The NaCl build is removed because I believe that all the pointers to it are in
the main Chromium repo and can be switched over. I'd rather get a clear build
error than linking in both OpenSSL and BoringSSL. (Also, forwarding doesn't
appear to work for NaCl targets.)

Remove header files in include/openssl.

This is needed because webrtc adds "../../openssl/openssl/include" to its
include directories explicitly rather than just using direct dependent
settings.

Switch openssl forwarding target to 'none'.

Building it as a static library causes problems on Mac at least since it's
empty.
