Make may not have copied "_libxl_types_json.h" into $(XEN_INCLUDE)
before starting to build the different objects.
Make sure that the generated headers are copied into $(XEN_INCLUDE)
before using them. This is achieved by telling make about which
headers are needed to use "libxl_internal.h" which use "libxl_json.h"
which uses "_libxl_types_json.h". "libxl_internal.h" also uses
"libxl.h" so add it to the list.
This also prevent `gcc` from using a potentially installed headers
from a previous version of Xen.

This is part of in review patch "libs/light: Rework targets
prerequisites", but that much smaller patch should be enough to fix
potential build issues.
This patch fix for example `make _libxl_types.o`, when libxl generated
headers aren't generated yet, and tools/light is clean.
For 4.17:
build fix.
