FFI::NotFoundError: Function 'SSL_library_init' not found in [libssl.so]

SSL_library_init was deprecated in OpenSSL 1.1.0 along with ERR_load_crypto_strings, and SSL_load_error_strings. They are called from https://github.com/lian/bitcoin-ruby/blob/master/lib/bitcoin/ffi/openssl.rb#L379.

Update ffi/openssl.rb to load openssl 1.0 if available
3a5cc93 
This updates the `ffi_lib` call to specify some alternative libraries which will
prioritize loading openssl 1.0. This fixes an issue on hosts which have openssl
1.1 and 1.0 and would encounter an error for the `SSL_library_init` function not
being found.

Fixes lian#205

Hi, is this a permanent fix? It definitely works for us, but it would be great if it was included in a published gem. Otherwise managing gems gets a bit more difficult (specific_install to the rescue).

Thanks for your great work!
