perf tools: Fix sb_evlist leaks in top and record
Fix a memory leak in cmd_top() where top.sb_evlist was not freed if
evlist__add_bpf_sb_event() fails. Note that evlist__start_sb_thread() and
evlist__stop_sb_thread() take ownership of the evlist and free it, so
we must only free it if we fail before starting the thread. Also set
top.sb_evlist to NULL to prevent use-after-free bugs.
Apply the same fix to builtin-record.c to avoid leaking rec->sb_evlist
and calling pthread_join on uninitialized threads in the error path.
