libxc: switch xc_dom_elfloader to be used with HVMlite domains

Allow xc_dom_elfloader to report a guest type as hvm-3.0-x86_32 if it's
running inside of a HVM container and has the PHYS32_ENTRY elfnote set.

Only xc_dom_elfloader has been switched to support HVMlite, other loaders
should also be switched once we have a HVMlite compatible kernel that uses
them.
