[CRIU] [PATCH 4/4] parasite, restore: Add EXPORT_SYMBOL for blob symbol definitions

[Cyrill Gorcunov]

Since we only need a few symbols from generated blob files
add EXPORT_SYMBOL helper -- it marks the symbols we want to
use and allows building script to find their offests.

This way extension of the scheme become easier: if one
need new symbol from blob -- just declare it with
EXPORT_SYMBOL helper.
