Pascal de Bruijn b02afdf32f package/linux-tools: add support for installing init system files
Some linux tools (e.g. the Microsoft HyperV convenience utilities) will
install programs tostart at boot time, so they need to be able to
install init files (systemd units, sysv init script, or openrc units).

Unlike the other commands, we are redefining the real _INSTALL_INIT_*
macros, rather than use hooks, to let the infra call those at the right
moment.

We must be careful about the openrc support, though: if two tools are
enabled, one which provides sysv scripts but no openrc config, and the
other which provides openrc config, and we are using openrc as init
system, then we want to use the sysv scripts from the former as well as
the openrc config of the latter. Thus we need to duplicate a bit the
openrc logic here.

# Instead, we directly build in the sources of the linux package. We can do
# that, because we're not building in the same location and the same files.
#
# So, all tools refer to $(LINUX_DIR) instead of $(@D).
# Note: we need individual tools makefiles to be included *before* we build
# the list of build and install hooks below to guarantee that each tool has
# a chance to register itself once, and only once. Therefore, the makefiles
# are named linux-tool-*.mk.in, so they won't be picked up by the top-level
# Makefile, but can be included here, guaranteeing the single inclusion and
# the proper ordering.
