certs: Move load_certificate_list() to be with the asymmetric keys code

Move load_certificate_list(), which loads a series of binary X.509
certificates from a blob and inserts them as keys into a keyring, to be
with the asymmetric keys code that it drives.

This makes it easier to add FIPS selftest code in which we need to load up
a private keyring for the tests to use.
