[CRIU] [PATCH] Fix Fedora compile (undo _FORTIFY_SOURCE for pie)

[Kir Kolyshkin]

Recent Fedora releases add -Wp,-D_FORTIFY_SOURCE=2 to rpm builds,
which breaks compiling pie code on some architectures due to its
trying to use (absent) memcpy_chk() instead of usual memcpy().

We must stand strong against FORTIFY_SOURCE in pie code.
No pasaran! Viva la resistance!

NOTE: in tests, FORTIFY_SOURCE is disabled for completely different
reasons (see commit d1a36cc for details), so we're not touching it.
