[workspace-dev] Incorrect file checks in mount-alter.sh

[Steffen Limmer]

Hello,

in mount-alter.sh $mountpoint is checked if it lies under the authorized
mountpoint directory.
But if mountpoint is in the form '../../<dir>' one can mount images to
arbitrary directories that are not under the authorized mountpoint
directory.
Please correct me if i'm wrong.

Regards,
Steffen
