Fix a rare but potential pre-exec child process deadlock in subprocess on POSIX systems when marking file descriptors inheritable on exec in the child process. This bug appears to have been introduced in 3.4 with the inheritable file descriptors support. This also changes Python/fileutils.c `set_inheritable` to use the "slow" two `fcntl` syscall path instead of the "fast" single `ioctl` syscall path when asked to be async signal safe (by way of being asked not to raise exceptions). `ioctl` is not a POSIX async-signal-safe approved function. ref: http://pubs.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html (cherry picked from commit c1e46e94de38a92f98736af9a42d89c3975a9919) Co-authored-by: Alexey Izbyshev <izbyshev@users.noreply.github.com>
