open_init_pty: Do not make stdin and stdout non-blocking
It is unclear why this was being done in the first place, and
it has caused multiple bugs with run_init/open_init_pty usage.

I see you fixed the issue with run_init/open_init_pty messing up with
the terminals but I think it's introducing an other issue :/
FTR I found the reason why stdin/stdout were not blocking, it's a fix
for this: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=474956#10
Apparently if the descriptors are closed, open_init_pty hangs, example:
./open_init_pty bash -c 'echo hello; exec >&- 2>&- <&-; sleep 1; '
