mount -o remount systemd incompatibility

mount's source code mentions that remount behaviour may not be
compatible with util-linux.
I can confirm that this is the case and it doesn't work with Systemd.
Systemd has a helper program to remount everything in fstab, since it
may have mounted it with the incorrect options. It is implemented by
reading /etc/fstab and shelling out to `/bin/mount -o remount $device`.
This is a no-op in busybox because remounting reads the mount options
from /etc/mtab.
