Define _KMEMUSER before including BSD kernel headers.

Recent versions of NetBSD hide certain kernel structures needed by the
KVM target from userland unless this macro is defined.

gdb/ChangeLog:

	* bsd-kvm.o: Define _KMEMUSER.
	* configure.ac: Define _KMEMUSER when checking for "struct lwp".
	* configure: Regenerate.
