setFlags
Sets the flags on the launcher.
The default flags are %G_SUBPROCESS_FLAGS_NONE.
You may not set flags that specify conflicting options for how to handle a particular stdio stream (eg: specifying both %G_SUBPROCESS_FLAGS_STDIN_PIPE and %G_SUBPROCESS_FLAGS_STDIN_INHERIT).
You may also not set a flag that conflicts with a previous call to a function like g_subprocess_launcher_set_stdin_file_path() or g_subprocess_launcher_take_stdout_fd().
