libmisc/shell: Fix the handling of joel scripts in telnet

Browse Source 
- Fix the passing of std[in/out] to child threads
- Fix deleting of managed memory in the key destructor
- Only set the key in the main loop thread
- Only allocate a shell env outside of the main loop
- Fix memory leak if the task start fails
- Remove error level from shell env, it cannot be returned this way. Add
  exit_code but the API is broken so it cannot be returned.

Closes #3859
