posix_spawn is less error-prone than vfork + execve, and can make
better use of system-specific enhancements like 'clone' on Linux. Use
it if we don't need to configure a pseudoterminal.
Backported from commit a60053f8368e058229721f1bf1567c2b1676b239.
Unlike that commit, only define USABLE_POSIX_SPAWN on macOS, because
there posix_spawn is much faster than vfork.
Don't merge to master.
