[CRIU][PATCH 1/3] zdtm: It's need turn off FORTIFY_SOURCE instead of use -Wno-unused-result option

[vkonyashkin]

The -Wno-unused-result option looks to have been introduced in GCC 4.5.0.
So it's need turn off FORTIFY_SOURCE (compiler warn about unused results
in fortification mode) instead of use -Wno-unused-result to avoid error
in versions prior to 4.5.0.
