Fix GC with XDG dirs, fixes #810

The environment variable used to set the root Stack directory was
incorrectly defined as STACK_ROOOT (typo with an extra 'O'). 

This has been fixed and the correct STACK_ROOT variable is now used.

See: https://docs.haskellstack.org/en/stable/environment_variables/#stack_root
