fix(linux): describe the right manual update path for deb/rpm hosts

A remote host installed from .deb or .rpm now reports
manual-service-update-required, and the guidance told the operator to
"update through the service manager that starts this server" -- which is
correct for unsupported-headless-serve but wrong for a package install,
where nothing about the remedy involves the service manager.

Say both, keyed on how the host was installed.
