valgrind: build ptests without optimizations

This commit changes the both CFLAGS and CXXFLAGS when building the
valgrind ptest binaries by appending -O0, forcing no optimizations
instead of the default -O2.  For qemux86-64, this change results in
FAIL/PASS ratio improvements from 149/394 to 58/485.

It is evident that the expected result files were generated from
regression tests binaries built without optimizations.
