The kernel doesn't actually tell us the name of the file we're exec'd
from. It passes an already open file descriptor. So we have to infer
the file name from /proc/self/exe. If that isn't available, we use
argv[0] (unless AT_SECURE) but that can be vastly different than
/proc/self/exe as it's a separate parameter in the execve() call (hence
unless AT_SECURE ;).
