perf diff: Use llabs() with 64-bit values
To fix this build error on a debian mipsel cross build environment:
builtin-diff.c: In function 'compute_cycles_diff':
builtin-diff.c:649:10: error: absolute value function 'labs' given an argument of type 's64' {aka 'long long int'} but has parameter of type 'long int' which may cause truncation of value [-Werror=absolute-value]
649 | val = labs(pair->block_info->cycles_spark[i] -
