vim-patch:9.1.0958: filetype: supertux2 config files detected as lisp

Problem:  filetype: supertux2 config files detected as lisp
Solution: detect supertux2 config files as scheme instead
          (Wu, Zhenyu)

References:

supertux uses #t and #f as bool type, which is same as scheme, not
common lisp
