qmake: eradicate Q_FOREACH loops [rvalues]

Browse Source 
... by replacing them with C++11 range-for loops.

This is the simplest of the patch series: Q_FOREACH took a
copy, so we do, too. Except we don't, since we're just
catching the return value that comes out of the function
(RVO). We can't feed the rvalues into range-for, because
they are non-const and would thus detach.
