libxenlight: two small fixes

- set the domid of the guest and not the one of the stubdom in the
libxl_device_model_starting returned to the user;

- check that the length of the two strings matches in
libxl_name_to_domid, otherwise we can get a match for two different
domains that have the same initial part of the name.
