From: Richard Maw <richard....@codethink.co.uk>
busybox's mount implementation doesn't re-read the options from
the fstab, it uses the flags it has in mtab.
This makes `mount -o remount $device` a no-op.
Rather than do string concatenation, add another -o option to the
list of parameters, since -o is cumulative.
