nail: fix build against OpenSSL with disabled SSLv3

Extend the existing patch handling disabled SSLv2 to cover the SSLv3 case as
well in order to fix the following build error reported by the buildbot:

    openssl.o: In function `ssl_open':
    openssl.c:(.text+0xa1c): undefined reference to `SSLv3_client_method'
    collect2: error: ld returned 1 exit status
