[libvirt] [PATCHv3] build: allow 'make syntax-check' on fresh checkout

[Eric Blake]

For good or for bad, I did a fresh checkout, ./autogen.sh, then
'configure', then 'make syntax-check', and was surprised that it
failed.  Running 'make' before 'make syntax-check' cleaned up the
issue, but this patch makes it work up front.

* cfg.mk (sc_po_check): Add prerequisites.

v3: also generate src/remote/remote_client_bodies.h
Thanks Laine for pointing it out to me on IRC.
