fix(provisioning): make latencytop/cockpit-tests install best-effort

global-installPackages installed latencytop and cockpit-tests on every
non-Kali host, but both have been dropped from Debian trixie (latencytop
is dead upstream; cockpit-tests has no candidate). Under the framework's
errexit the failing apt-get aborted the entire run with rc=100 right
after the core package install completed.

These are optional monitoring/test extras, not core requirements, so
make the install best-effort with `|| true` to match the script's
existing treatment of non-critical operations.
