fsmgr: support multiple fs-types/mountpoint
Previous attempt was broken.
It would incorrectly be affected by mount failures.
This changes allows an fstab to contain multiple lines for a given
mount point.
The lines sharing a mount MUST be after each other.
The 1st matching line is the primary when it comes to mounting
and look ups for wiping.
Mounting based on a mount_point will attempt each dup in turn
until one succeeds.
The reported error will be that of the last failed attempt.
This is to allow quick experimentation between different FSes.
