Alexander Egorenkov 1f68c1aaf3 zdump/ngdump: Perform sanity checks on path to dump image ...

Ensure that the path to a dump image specified in the NGDump meta file
of a dump device points to a valid location within the dump device.
Especially, disallow escaping from a dump device with a dump image path
using references to '..' or symbolic links pointing outside of the dump
device.
