[CRIU] [PATCH v3] make: fix blob dependencies

[Kinsbursky Stanislav]

From: Stanislav Kinsbursky <skinsbursky at openvz.org>

v3:
1) "crtools" ($(PROGRAM)) goal dependences fixed.

v2:
1) wrong "protobuf/tmp.pb-c.h" inclusion removed from cr-dump.c

Without this patch "touch parasite.c" will lead to rebuild of the whole
project.
This patch also introduces "pie" goal as a subsystem. This will be usefull,
when other subsystems will apper, because it allows to build them in parallel.
"all" becomes default goal. This allows to skip deps inclusion for empty,
"all", "zdtm" and "test-legacy" goals.
