swift-drive-audit: reload systemd after editing fstab
Systemd does not monitor /etc/fstab for changes; so a filesystem
unmounted and commented-out in fstab will be re-mounted by systemd
after some time.
This change means that swift-drive-audit will call systemcl
daemon-reload (which causes systemd to reload its configuration
including /etc/fstab) after editing /etc/fstab on systems where
systemd is the running init. Check for that case by looking for the
existence of the directory /run/systemd/system, as documented in
sd_booted(3).
