Latest clang uses openat(2).
If the pathname is absolute or dirfd is AT_FDCWD we can handle it exactly like open(2). Otherwise we output an A record to indicate that the path of an open directory needs to be used (earlier in the trace).
Also filemon_pid_check needs to hold proctree_lock and use proc_realparent()
