SPAWN_NO_PARENT_ENVV

Use this as a spawn flag (together with flags from #GSpawnFlags) in vte.pty.Pty.spawnAsync.

Normally, the spawned process inherits the environment from the parent process; when this flag is used, only the environment variables passed to vte.pty.Pty.spawnAsync etc. are passed to the child process.
