populate_sdk_qt5.bbclass: Fix symlink location for QtCreator use

The QtCreator is quite broken regarding finding the mkspecs files; so
to workaround it we must to add a symlink to it. The workaround was in
place but in the wrong sysroot, it must to be in the /native/ one.

nativesdk-qtbase-tools: disable Debian-style package renaming

Since commit 8da5017712a7ddcb8488e095b9aa03b0273f23e9, libQt5*.so files
are included in the nativesdk-qtbase-tools package. However, this together
with the fact that the binaries are placed in a subdir "qt5" of bin will
confuse the Debian-style package renaming logic in debian.bbclass, causing the
resulting ipk package to be created as "nativesdk-libqt5core5".

populate_sdk_qt5.bbclass: Add support for qtcreator-debug

This adds a new image feature for easier remote debugging with
QtCreator.

The qtcreator-debug needs to be added as a valid item for image
features and having it inside the populate_sdk_qt5 is too late. User
will see a parser error as OE-Core images does not inherit the classs.
The possible workaround for it is to include it inside layer.conf file
until a kind of "bbclassappend" support is in place.
