42427e9e29 sched/taskfiles: skip unnecessary file open/close operations to improve performance
The task files should consult the "spawn action" and "O_CLOEXEC flags"
to determine further whether the file should be duplicated.

This PR will further optimize file list duplicating to avoid the performance
regression caused by additional file operations.

c33d1c9c97 sched/task/fork: add fork implementation
1. as we can use fork to implement vfork, so we rename the vfork to
fork, and use the fork method as the base to implement vfork method
2. create the vfork function as a libc function based on fork
function
