vma: Add !VVAR condition to vma_entry_can_be_lazy

AFAIU Currently most of the times we don't have problems with VVAR segment due
to during parking vdso on it's old place mremap is used and during it
munmap is called to destination address which results in calling
UFFDIO_UNREGISTER. But as for VDSO we don't want to enable uffd for these addresses at firse place.
