iOS (OSX): rework how to bundle QML import folders

Before this patch, we would copy "$QTDIR/qml"
directly into the bundle as "qml". This would cause problems
if the user also tried to deploy qml files to a "qml" folder, or
if any other file in the bundle ended up with the name "qml" (which is the
case for QtDeclarative/tools/qml, where the executable is called "qml").

This patch will instead copy the contents of each import folder
into QMAKE_QML_BUNDLE_PATH, which will default to "qt_qml" on iOS
and "Resources/qt_qml" on OSX.

We also change the implementation to use a post script rather
then QMAKE_BUNDLE_DATA for two reasons:
1. Xcode does not like "copy build phases" to copy folders, only
    files (You cannot even create such a phase from Xcode, although
    it is possible to force it the way we create project.pbx. But
    this was error prone)
2. We need to strip away unneeded files from the bundle, like
    archives (which are linked in statically, not dlopened run-time).
    Using rsync lets us copy and strip in one operation.
