[OE-core] [PATCH dylan, master] Fix meta-toolchain-qte SDK build for x11-less DISTRO

[Nicolas Dechesne]

When building QTe SDK for a DISTRO that does not have x11 FEATURES,
building meta-toolchain-qte failed because it unconditionally pulls in
nativesdk-libx11. The 'culprit' is meta/recipes-qt/qt4/nativesdk-qt4-tools.inc.

The fix is inspired from the following commits:

abf2ab7 dbus: only use x11 if DISTRO_FEATURES has selected it
ba22cfa cairo: only use x11 if selected in DISTRO_FEATURES
