perf trace: Free syscall tp fields in evsel->priv
ASan reports several memory leaks running: # perf test "88: Check open filename arg using perf trace + vfs_getname" The third of these leaks is related to evsel->priv fields of sycalls never being deallocated. This patch adds the function evlist__free_syscall_tp_fields which iterates over all evsels in evlist, matching syscalls, and calling the missing frees. This new function is called at the end of trace__run, right before calling evlist__delete.
