Revert "x86_64: Suppress false positive valgrind error"
This reverts commit a1735e0aa858f0c8b15e5ee9975bff4279423680.

The test failure is a real valgrind bug that needs to be fixed before
valgrind is usable with a glibc that has been built with
CC="gcc -march=x86-64-v3".  The proposed valgrind patch teaches
valgrind to replace ld.so strcmp with an unoptimized scalar
implementation, thus avoiding any AVX2-related problems.
