Ruowen Qin 9e09b75079 samples/bpf: Add -fsanitize=bounds to userspace programs 
The sanitizer flag, which is supported by both clang and gcc, would make
it easier to debug array index out-of-bounds problems in these programs.

Make the Makfile smarter to detect ubsan support from the compiler and
add the '-fsanitize=bounds' accordingly.
