This is analogous to #70447.
With security.lockKernelModules=true, docker commands result in the following
error without at least loading veth:

The bin script that runs chromium calls out to gnugrep - but gnugrep is
missing as a runtime dependency of the chromium package. I found this
out when I was trying to put it in a docker image.
"bazel fetch" will, by default, fetch everything that _might_ be used,
including things that will later be discarded due to the way the build
is configured.
Concretely, this means that for some builds of Java packages, this will
avoid failures where the builder tries to retrieve the JDK from /usr/share/java
(or equivalent).
This also means that for most packages we can fetch _fewer_ dependencies,
since the standard tree pruning for artifacts to fetch will take effect.
fetchConfigured is disabled by default since it changes the fetch hashes
of tensorflow/tensorflow2 (since it ends up fetching less).
This change was preceded by the idea of adding a pronoun field to the
file, which we determined to be a bad idea:
* maintainers-list: add pronoun to the optional fields
I often do not know how to address maintainers, so giving them the
ability to specify their pronouns is helpful for communication
purposes.
* maintainers-list: add pronoun for Profpatsch
maintainers-list: make the pronoun field into a list
Some people have a set of pronouns they are fine with, so let’s make
that possible.
Based on feedback by somebody With An Idea™ of the topic.
* maintainers-list: remove the pronouns field
The discussion around the field raised a good point, quoting:

So let’s remove it again.
