Make the parse_certificate_fuzzer from libpki work inside boring.

Seed the corpus from cert_corpus. As part of that, check in the result of minimizing all the corpora.

Note this is just making one of the fuzzers build, I'll adapt
the others and follow on by updating the IMPORT process to do it
in a follow on cl.
