distro/installer related graph cleanup

As was duly noted by Leo-sp50, both server.mk and desktop.mk
duplicate a few bits layered over bare distro/installer which
happened to be both a dependency (thus should reduce redundancy)
and a "real distro" target (well, it doesn't just work yet, need
to provide networking and sources.list in install2 by hand).

Fixed by moving a "node" to distro/.installer along with typical
additions and leaving a bare installer as is by now; there's a
need to get it working at least for DHCP/ftp.altlinux.org case.
