QMimeDatabase: Run more tests on non-XDG/shared-mime-info platforms

On Windows and OS X, where QStandardPaths does not use XDG_DATA_DIRS/
_HOME and shared-mime-info is not installed, the tests that require
additional shared mime info xml files were never run.
Mend that by using QStandardPaths' test mode instead of setting
XDG_DATA_HOME.
