Improve file handling in test of QSettings.

- Avoid duplication of slashes and use static variable for the
  const part in settingsPath().
- Do not run expensive cleanup twice in init()/cleanup() as was
  before by moving the code into a separate cleanupTestData()
  function called from cleanup() and initTestCase().
- Use QDir::removeRecursively() (which should be able to deal
  with readonly files, etc after 26bcc0565f49c731a4f288f93f04056ca20136a5 )
  instead of system calls or the special removePath() function for
  CE/RT.
- Switch QStandardPaths into test mode.
