Subject: [PATCH 1009/1009] Drop or soften some of the deprecation warnings

- Don't taint systems using the hybrid hierarchy since it's the default on SLE.

- Reword the deprecation warning about KillMode=none (bsc#1193086)

- Decrease log level of messages about use of KillMode=none (jsc#PED-944)

[fbui: fixes bsc#1193086]
[fbui: fixes jsc#PED-944]
