Copy patch from lang/qt5-qml to fix the build with base GCC.

Since r372179 we are using the QML headers from the tarball, not the ones
installed system-wide by qt5-qml.

While this is not a problem and is kind of intended, it also means we need
to apply patches like this one to both ports now.

Add upstream patch to fix a filtering bug in KMail.

Despite what the patch's commit message says, this is actually a fix for
https://bugs.kde.org/show_bug.cgi?id=340015, which is part of 4.14.3. It
allows filtering based on the "List-Id" header to work again.
