xen/gntdev: Use select for DMA_SHARED_BUFFER
DMA_SHARED_BUFFER can not be enabled by the user (it represents a library
set in the kernel). The kconfig convention is to use select for such
symbols so they are turned on implicitly when the user enables a kconfig
that needs them.
Otherwise the XEN_GNTDEV_DMABUF kconfig is overly difficult to enable.
