When neither VIRTIO_PCI_LIB nor VIRTIO are enabled, but the alibaba
vdpa driver is, the kernel runs into a link error because the legacy
virtio module never gets built:
x86_64-linux-ld: drivers/vdpa/alibaba/eni_vdpa.o: in function `eni_vdpa_set_features':
eni_vdpa.c:(.text+0x23f): undefined reference to `vp_legacy_set_features'

When VIRTIO_PCI_LIB was added, it was correctly added to drivers/Makefile
as well, but for the legacy module, this is missing. Solve this by always
entering drivers/virtio during the build and letting its Makefile take
care of the individual options, rather than having a separate line for
each sub-option.
