Subject: [PATCH] Removed unnecessary dependencies of `codegen_init.o` for
 unsecure build.

`codegen_init.cc` is listed in `LIBGRPC++_UNSECURE_SRC`, which are
compiled without SSL, but in `Makefile` lists SSL-required libraries as
its dependencies. Since the file itself does not use any bits from those
libraries, it is safe to remove those dependencies.

Subject: [PATCH] CMake: Automatic fallbacking on system's OpenSSL if it only
 has NPN.

Since ALPN is not supported on some old systems that come with OpenSSL
version 1.0.1 or older, gRPC needs to fall back to NPN when being built
with these systems' OpenSSL.
