Subject: [PATCH 10/11] Make root's home directory configurable

OpenEmbedded has a configurable home directory for root. Allow
systemd to be built using its idea of what root's home directory
should be.

Upstream-Status: Denied
Upstream wants to have a unified hierarchy where everyone is
using the same root folder.
