Compile Private API autotests for INTEGRITY

- GHS's __PRETTY_FUNCTION__ (used by QT as Q_FUNC_INFO) doesn't have spaces
  round the = operator when indicating the type of the template parameter.

 The compilation error:
 qt5/qtbase/src/corelib/kernel/qmetatype.h", line 2104: note #3316-D:
 cannot access position 53 in array of 49 elements
 constexpr const char *begin = func + prefix;
