[PATCH] resolvconf: check if running systemd in postinst

[Jonathan Liu <net147@gmail.com>]

Check if running systemd in postinst by testing for existence of
/sys/fs/cgroup/systemd instead of checking if systemd-tmpfiles
exists in PATH. This is so populate-volatile.sh update is called
instead of systemd-tmpfiles --create if the system has
systemd-tmpfiles installed but was booted using sysvinit.
