parse.y: Fix locations of xstring

• parse.y (new_xstring_gen): Always set locations
  to include locations of tXSTRING_BEG and tSTRING_END.

  e.g. The locations of the NODE_XSTR is fixed:

  `a`
  

  • Before

  NODE_XSTR (line: 1, code_range: (1,1)-(1,2))
  

  • After

  NODE_XSTR (line: 1, code_range: (1,0)-(1,3))
