QKdeTheme: de-inline dtor; make ctor explicit

Browse Source 
1/
A QStringList and an int are not a faithful representation of a KDE
Theme, so the ctor should be explicit. Make it so™.

2/
As a polymorphic class, the (undeclared, therefore inline) dtor may
cause weak vtables to be emitted, with all the bad side-effects
described in the docs of -Wweak-vtable and QTBUG-45582. Mark the dtor
out-of-line in the usual way (= default'ing, but in the .cpp file).

Amends 53fb13456fffe8bfd192f9197c6d1703854b49a2.
