dongjiuzhu1 18819b6b24 sched/task: close file descriptor with O_CLOEXEC before active task or exec 
VELAPLATFO-18473

refs:
https://man7.org/linux/man-pages/man2/fcntl.2.html
If the FD_CLOEXEC bit is set, the file descriptor will automatically
be closed during a successful execve(2).
(If the execve(2) fails, the file descriptor is left open.)

modify:
1. Ensure that the child task copies all fds of the parent task,
   including those with O_CLOEXE.
2. Make sure spawn_file_action is executed under fd with O_CLOEXEC,
   otherwise it will fail.
3. When a new task is activated or exec is called, close all fds
   with O_CLOEXEC flags.
