Summary:
- I noticed that adb shell failed when sh is spawned.
- Finally, I found that an error happened when executing dup2() action
if the file descriptor has the O_CLOEXEC option.
- This commit fixes this issue by dropping the option in the API.
Impact:
- posix_spawn_file_actions_adddup2() only
Testing:
- adbd with sabre-6quad:netnsh (will be merged later)
