tools/libs/ctrl: use common p2m mapping code in xc_domain_resume_any()

Instead of open coding the mapping of the p2m list use the already
existing xc_core_arch_map_p2m() call, especially as the current code
does not support guests with the linear p2m map. It should be noted
that this code is needed for colo/remus only.

Switching to xc_core_arch_map_p2m() drops the need to bail out for
bitness of tool stack and guest differing.
