Merge the md_page structs for AIM and Book-E into a single unioned struct

Summary:
Ports like sysutils/lsof troll through kernel structures, and
therefore include kernel headers and all the dirty secrets involved.  struct
vm_page includes the struct md_page inline, which currently is only defined
if AIM or BOOKE is defined.  Thus, by default, sysutils/lsof cannot build,
due to the struct md_page having an incomplete type.  Fix this by merging
the two struct definitions into an anonymous struct-union.

A similar change could be made to unify the pmap structures as well.
