tox: don't cap pyopenssl to 0.13tox_pyopenssl

pyopenssl 0.13 cannot be installed on my Fedora 23. It fails with:

    building 'OpenSSL.crypto' extension
    (...)
    OpenSSL/crypto/crl.c:6:23: erreur: static declaration of ‘X509_REVOKED_dup’ follows non-static declaration

                   ^
    error: command 'gcc' failed with exit status 1

The bug is known: https://github.com/pyca/pyopenssl/issues/276

The workaround is simple: use a more recent version.
