tst_QCompareHelpers::compareWithAttributes(): do not generate deprecation warnings

Browse Source 
Some compilers do not respect the

  QT_WARNING_PUSH
  QT_WARNING_DISABLE_DEPRECATED
  ...
  QT_WARNING_POP

incantation, so rewrite the test to use `template <typename X>` as
an Attribute parameter of the macros.
This allows to get rid of annoying warnings when compiling
tst_qcomparehelpers.

Amends de16185068a08e0cab8bf588c574899a19392410.
