Similar to `os.system` (which is already raising auditing event), the following functions are also capable of command execution, so they also need auditing:

- os.execl
- os.execle
- os.execlp
- os.execlpe
- os.execv
- os.execve
- os.execvp
- os.execvpe
- os.posix_spawn
- os.posix_spawnp
- os.spawnl
- os.spawnle
- os.spawnlp
- os.spawnlpe
- os.spawnv
- os.spawnve
- os.spawnvp
- os.spawnvpe
- os.startfile
- pty.spawn

By the way, since `os.listdir`, `shutil.copytree` and `shutil.rmtree` are already being audited, is it necessary to audit file operations in the `os` module like `os.remove`?
