system: Declare qemu_[min/max]rampagesize() in 'system/hostmem.h'

Browse source 
Both qemu_minrampagesize() and qemu_maxrampagesize() are
related to host memory backends, having the following call
stack:

  qemu_minrampagesize()
     -> find_min_backend_pagesize()
         -> object_dynamic_cast(obj, TYPE_MEMORY_BACKEND)

  qemu_maxrampagesize()
     -> find_max_backend_pagesize()
        -> object_dynamic_cast(obj, TYPE_MEMORY_BACKEND)

Having TYPE_MEMORY_BACKEND defined in "system/hostmem.h":

  include/system/hostmem.h:23:#define TYPE_MEMORY_BACKEND "memory-backend"

Move their prototype declaration to "system/hostmem.h".
