tst_QTemporaryFile: replace custom struct with QScopeGuardHEADdev

Simplify the code by using QScopeGuard. In particular, this makes
clear what "reset()" was supposed to do: dismiss.

Every Qt developer knows the semantics of QScopeGuard, but this custom
class has to be learned by every reader anew.

As a drive-by, fix the spacing inside parentheses.

Amends the start of the public history.
