tools/hotplug: Removing of "all" dependency from "install" rule.

The "install" rules depends on both "all" and "subdirs-install" and
"all" depends on "subdirs-all". This leads the "install" rules to call
both "subdirs-all" and "subdirs-install" which create a race with two
concurrent `make` within the same directory (systemd) trying to make the
same things (xen.conf) and failing.

Ultimatly, "install" should only depend on the things it needs to
install, and not on "all".
