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.
