libfortran/90038: Use posix_spawn instead of fork
fork() semantics can be problematic. Most unix style OS'es have
posix_spawn which can be used to replace fork + exec in many cases.
For more information see
e.g. https://www.microsoft.com/en-us/research/uploads/prod/2019/04/fork-hotos19.pdf
This replaces the one use of fork in libgfortran with posix_spawn.
