tests/smime: Include the Sample LAMPS Certificate Authority

This CA is useful for test suites and the like, but is not an
actually-secure CA, because its secret key material is also published.

I plan to use it for its intended purpose in the notmuch test suite.

It was copied from this Internet Draft:
