[CRIU] [PATCH 5/5]v5 zdtm: test for auto-dedup on restore

[Tikhomirov Pavel]

if new size of image is zero than dedup works

use :
bash test/zdtm.sh -A static/maps04
bash test/zdtm.sh -P -i 3 -A -t transition/maps007

changes: aplicable for all tests, -ad changed to --auto-dedup,
simplify, check all(and only) private pages files.
