perf c2c: Rename for shared cache line stats
For shared cache line statistics, 'perf c2c' relies on HITM. We can use
more general naming rather than only binding to HITM, so replace
"hitm_stats" with "shared_clines_stats" in structure perf_c2c, and
rename function resort_hitm_cb() to resort_shared_cl_cb().
