Josh Patterson 21222ff119 FIX: use /sbin/nologin for service accounts
These accounts existed only for container UID mapping and filesystem
ownership, but user.present omitted shell:, so Salt fell through to the
platform useradd default and every one of them got /bin/bash. Pin them to
/sbin/nologin so none can be used as an interactive login or `su -` target.

socore keeps /bin/bash: `su socore -c '/usr/sbin/so-repo-sync'` in soup and
so-kernel-upgrade execs the account's passwd shell, and operator docs tell
users to su to socore. soqemussh keeps /bin/bash as an SSH login account.

elastic-agent, elastic-agent-pr and kafka are included alongside the accounts
named in the issue, being the same class with the same unset shell, so the
default is uniform.

Cron is unaffected: cronie runs jobs via the crontab SHELL (default /bin/sh),
not the passwd shell. suricata is the only account changed here that owns a
crontab, and somon has shipped as nologin with a working cron job already.
The zeek `runuser -l zeek` calls all run inside so-zeek via docker.run/exec,
so they resolve the shell from the image, not the host.

Verified on a 3.4.0 managersearch + sensor grid: highstate converges with the
shell as the only change and no failures, is idempotent on a second run, all
containers stay up, SOC still issues a Kratos login flow, and the suricata
surilogcompress cron job runs post-change ((suricata) CMD/CMDEND in
/var/log/cron) while `su - suricata` is now refused.

Closes #16256
