description:
conditionally put back the include of <uvm/uvm_page.h>

This is a kludge to fix the build on some ports. According to pmap(9),
including <uvm/uvm_extern.h> should be sufficient to use
"bool pmap_is_modified(struct vm_page *pg)". However, on several ports,
the function is implemented as a macro and depends on implementation
details of "struct vm_page *", which is normally an incomplete forward
declaration only. XXX revert when all ports are fixed.
