In an automated build system, where valgrind and ffmpeg get updated in
parallel, a race condition may occur in which valgrind/valgrind.h is
available when configure runs but not if libavutil/log.c gets compiled.

Using CONFIG_VALGRIND_BACKTRACE helps to avoid this problem, because
it allows to prevent the inclusion of the autodetected valgrind.h by
using a configure switch.
