Remove SSL initializer from the prober (#378)

The prober now uses the common SSL initializer in the networking
subproject.

Also changed both initializers to take an ImmutableList of certificates
other than an array of those, for better immutability.

I have no idea where these lockfile changes are coming from. They seem
to be pure noise as far as code review is concerned.
