Miss Islington (bot) 2bb0bfafb0 bpo-32777: Fix _Py_set_inheritable async-safety in subprocess (GH-5560) (GH-5562) 
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.

(cherry picked from commit c1e46e94de)
