mach-defpager: fix receiver lookups

Previously, the receiver lookup was done manually in all the server
functions.  Use mig translator functions instead.

* mach-defpager/mig-decls.h: New file.
* mach-defpager/mig-mutate.h: Likewise.
* mach-defpager/Makefile (MIGSFLAGS): Include mig-mutate.h.
* mach-defpager/mach-defpager.c: Fix receiver lookups, move type
definitions...
* mach-defpager/priv.h: ... here, so that they can be used in
mig-decls.h.
