Enable nativesdk-qtbase to keep additional libraries

We have a usecase where we need to run a tool to transform a protocol spec. to cpp (kdwsdl2cpp). That tool is built using Qt5, and requires a couple of extra Qt-libraries, among the libQt5Xml.so.*. Today the nativesdk-qtbase recipe just unconditionally removes every library, except for a couple hardcoded ones.

This patch add an extra variable, in which you can specify additional libraries to keep.

2.1.1

In some usecases for the nativesdk, you might need some build tools that are built upon Qt5. This means that we're having a need to keep more of the libraries build by nativsdk-qtbase. This patch adds the infrastructure to support that
