travis: use clang's -fsanitize=address to catch more bugs

The clang address sanitizer is able to catch quite a number of
memory-related bugs, such add memory leaks and buffer under/overruns.
So, enable the address sanitizer for one openssl and one mbedtls build.

This would have caught the buffer list unittest memory leak that
<1512724338-22197-1-git-send-email-steffan@karger.me> wants to fix.
