xen: add a meaningful declaration of grant_copy_segment into xen_common.h
Currently the xen_disk source has to carry #ifdef exclusions to compile
against Xen older then 4.8. This is a bit messy so this patch lifts the
definition of struct xengnttab_grant_copy_segment and adds it into the
pre-4.8 compat area in xen_common.h, which allows xen_disk to be cleaned
up.
