[CRIU] [PATCH 5/5] vdso: Implement vDSO proxification of any vvar/vdso order

[Cyrill Gorcunov]

In latest linux-next the vdso zone is placed _after_ vvar
zone so eventually we need to handle any combination of
the following cases

 - no vvar zone
 - vvar before vdso
 - vvar after vdso

Here we address all them.
