[PATCH 2/3] systemd: replace the sysusers.d basic configuration

[Louis Rannou <lrannou@baylibre.com>]

The default sysusers basic.conf.in file sets the root home directory to `/root`
and does not permit its configuration. Replace the file delivered by systemd so
the root home directory matches the `ROOT_HOME` variable.
