perf synthetic-events: Fix stack buffer overflow and bounds in cgroup synthesis
Fix a pre-existing stack buffer overflow bug in
perf_event__synthesize_cgroup() where an in-place null padding loop wrote
bytes past the end of the cgrp_root stack array buffer during cgroup tree
traversal. Eliminate in-place path mutation, use PERF_ALIGN for path_len,
clamp raw_path_len to prevent sample ID header trailer overruns, and use
strlcpy with combined zero padding for alignment and sample ID headers.
