Needs a dependency on ca_root_nss

[llmII]

Before I added the depedency on ca_root_nss, the following error occured:

# log from freebsd_14-0-x64-default-desktop/2023-12-16_21h31m23s/logs/libtensorflow1-1.15.5_1.log
error running 'git fetch --all' while working with @io_bazel_rules_docker:
fatal: unable to access 'https://github.com/bazelbuild/rules_docker.git/': SSL certificate problem: unable to get local issuer certificate

After I added ca_root_nss to BUILD_DEPENDS (not showing a diff, I did the bare minimum to make it a depedency and is definitely not how it would normally be done for a port am sure) it built fine.

I'm unsure but maybe in the past one of this port's dependencies automatically brought in ca_root_nss and that's no longer the case. It could also be the manual configuration applied to the ports this port depends on that I have made that is a difference as well.

All ports I build are built with poudriere so essentially would not have ca_root_nss installed as part of the system since the system is a clean system.
