Revert "src: fix missing extra ca in tls.rootCertificates"

A fix to tls.rootCertificates to have it correctly return the
process' current root certificates resulted in non-deterministic
behavior when Node.js is configured to use an OpenSSL system or
file-based certificate store.

The safest action is to revert the change and change the specification
for tls.rootCertificates to state that it only returns the bundled
certificates instead of the current ones.
