libutils: disable word-at-a-time for str* functions with ASan

The optimized versions of str* functions perform word-aligned reads
that may go slightly past the actual string boundary. The out-of-bound
read accesses doesn't look dangerous, because in this case buffer start
address is always word-size aligned.

Disable the optimized versions when CFG_CORE_SANITIZE_KADDRESS is enabled
to avoid ASan errors.
