Subject: [PATCH] Only initialize existing Net::SSLeay methods

Recent OpenSSL can be built without engine support and then Net-SSLeay
is missing ENGINE_load_builtin_engines() and
ENGINE_register_all_complete() subroutines. In that case
t/Port_Configuration.t failed like this:

    $ prove -l -v  t/Port_Configuration.t
    t/Port_Configuration.t ..
    1..51
    [...]
    ok 34 - run ( ipv => '*', port => 'foo/bar/unix' )  ==>  [ '*|foo/bar|UNIX|*' ]
    # Unable to load module for proto "Net::Server::Proto::SSLEAY": Can't use an undefined value as a subroutine reference at /home/test/fedora/perl-Net-Server/perl-Net-Server-2.014-build/Net-Server-2.014/lib/Net/Server/Proto/SSLEAY.pm line 31.

    }],

      NS_listen => 4096,
      NS_port => 20203,
      NS_proto => 'SSLEAY',
      SSL_cert_file => 'somecert'
    }]
    }
    # number of tests ran 35 did not match number of specified tests 51
    Failed 17/51 subtests

This patch calls the Net::SSLeay initialization routines only if they are defined.
