mksquashfs: fix dir_scan5() -- empty prune action

Dir_scan5() did not check for root entries (entries in the root
directory read from the original filesystem in append mode).

These entries are not "real" entries in that they cannot be evaluated
for emptiness.  The entries only exist in the original filesystem
amd must be skipped.
