When the kernel and hence vDSO are built with BTI enabled force the linker to link the vDSO as BTI. This will cause the linker to warn if any of the input files do not have the BTI annotation, ensuring that we don't silently fail to provide a vDSO that is built and annotated for BTI when the kernel is being built with BTI.
