posix.c and minios.c implement the same named functions serving slightly
different purposes.
For xenbus_map()
posix.c maps the local /dev/xen/xsd_kva
minios.c maps dom0 via grant and there is open coding for stub_domid in
map_interface.
Change xenbus_map() to map the local domain's interface. The default
grant table mapping is performed otherwise.
