mdmon: Remove need for KillMode=none
mdmon needs to keep running during the switchroot out of (at boot) and
then back into (at shutdown) the initrd. It runs until a new mdmon
takes over.
Killmode=none is used to achieve this, with the help of --offroot which
sets argv[0][0] to '@' which systemd understands.
This is needed because mdmon is currently run in system-mdmon.slice
which conflicts with shutdown.target so without Killmode=none mdmon
would get killed early in shutdown when system.mdmon.slice is removed.
As described in systemd.service(5), this conflict with shutdown can be
resolved by explicitly requesting system.slice, which is a natural
counterpart to DefaultDependencies=no.
So add that, and also add IgnoreOnIsolate=true to avoid another possible
source of an early death. With these we no longer need KillMode=none
which the systemd developers have marked as "deprecated".
