[CRIU] [PATCH 05/11] vdso/restorer: Simplify vdso/vvar order checking

[Dmitry Safonov]

Ordering check for vvar/vdso blobs was introduced with
the commit b00bdb2dbc31 ("vdso: x86 -- Test VMAs order in vdso_proxify")
Let's simplify it to more readable version.
As above we've compared that vvar/vdso's blob size from dumpee matches
sizes of rt-vvar/rt-vdso, kill that xor here.
