test: check crypto before requiring tls module

test-tls-session-cache currently fails if built --without-ssl:
internal/util.js:82
    throw new errors.Error('ERR_NO_CRYPTO');
    ^

Error [ERR_NO_CRYPTO]: Node.js is not compiled with OpenSSL crypto

The test has a crypto check but it come after the require of the tls
module.

This commit moves the crypto check to come before the require of tls and
allows the test to pass.
