[musl] Re: Tweaking the program name for <err.h> functions

Yup, I agree. My confusion was from an incorrect assumption that
non-suid / suid programs would be handled the same way. I knew that
strace wouldn't keep it setuid by I didn't realize glibc only checked
closed fds for suid programs (which makes sense, this doesn't matter
for non-privileged programs).

And hopefully no program does that, and if it does, that's their fault :)
