[CRIU] [PATCH 3/3] crtools: fix exit code for page-server

[Andrei Vagin]

From: Andrei Vagin <avagin at virtuozzo.com>

cr_page_server() returns pid, if it is executed as a daemon
otherwise it returns an error code.

crtools returns 0 only if cr_page_server() returns a positive value,
what is obviously wrong.
