set 8MB user stack size, add more flags for sys_clone
...
8MB is the default linux app stack size on x86_64.
gcc app in alpine linux call sys_clone with flags 0x5d0f00.
In case of supporting more other potential flags,
use panic! instead of warn!, then we can get timely panic-style info.
Now python2 hello.py can run correctly, but only one time.
I guess the memory management has some problem,
maybe there are some memory leak.

fix bug: sys_exec should name as exec_path, then loader can find the exec file.
...
items of VEC args from argv is the args lists, and args[0] isn't the complete exec_path.
the new_user function should add exec_path as a new args.
BUGS:
ls app doesn't show any thing. Why?
