VM: fix pageout of external objects backed by the default pager
Double paging on such objects causes deadlocks.
* vm/vm_page.c: Include <vm/memory_object.h>.
(vm_page_seg_evict): Rename laundry to double_paging to increase
clarity. Set the `external_laundry' bit when evicting a page
from an external object backed by the default pager.
* vm/vm_pageout.c (vm_pageout_setup): Wire page if the
`external_laundry' bit is set.
