fix(build): define CBM_SANITIZED_BUILD in TSan flags too

CFLAGS_TEST/CXXFLAGS_TEST already define CBM_SANITIZED_BUILD via
SANITIZED_DEFINE, but CFLAGS_TSAN/CXXFLAGS_TSAN never did. This left
mem_override_posix.c's !defined(CBM_SANITIZED_BUILD) guard always true
under make test-tsan, compiling __wrap_free/__wrap_realloc (with their
__real_free/__real_realloc forward declarations) into a link that never
passes -Wl,--wrap=... — undefined reference at link time.
