Generate certs on the fly in runner, pass trusted cert to shim

Rather than using the pre-generated certificates, generate them on the
fly. This allows TLS stacks for which certificate validation and
verification are coupled to work as expected. Certificates and keys are
written to temporary files which are then passed to the shim, and
cleaned up on exit. This requires reworking how testCase passes
certs/keys by adding a new field, sendCertificate, rather than manually
setting the -cert-file and -key-file flags. Incidentally the
rsaChainCertificate is removed, since it was essentially unused, and all
tests that used it also work with rsaCertificate. Finally, include a
single SAN ("test") in all certificates, which fixes some TLS stacks
which require this to operate (such as rustls, which currently
regenerates all the certificates currently in the tree to add a SAN).

Additionally, add a new flag, -trust-cert, which tells the the shim
which certificates it should trust. Shims for TLS stacks which
can completely decouple validation and verification of X509 certificates
(like BoringSSL) can ignore this flag, but for stacks where this
functionality is somewhat more intertwined (like Go), this allows the
shim to properly process the sent certificates.

BoringSSL

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.

Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.

Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.

BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.

Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
