Francis Laniel a15e35c4eb falcosecurity-libs: add new package
This is a dependency of newer sysdig. It contains the driver, and also a
few userspace components. The latter however are not meant to be
installed in the sysroot; instead, the whole thing is meant to be
included directly in the build of the project using it. Changing things
so it does work in the normal way of installing to the sysroot turns out
to be pretty complicated.

Basically, falcosecurity-libs is just a component of sysdig. It's
defined as a separate package only because that's an easier way to
download it than defining extra download and extract commands in sysdig
itself. For this reason, it's defined as a blind option in Config.in.

# falcosecurity-libs creates the module Makefile from a template, which contains
# a single place-holder, KBUILD_FLAGS, wich is only replaced with debug flags,
# which we don't care about here.
# So, just replace the place-holder with the only meaningful value: nothing.
# For the DRIVER_NAME, we set it to FALCOSECURITY_LIBS_DRIVER_NAME.
# So, when sysdig will be run, it will automatically load
# FALCOSECURITY_LIBS_DRIVER_NAME.ko.
# We also need to do the same process for driver_config.h.in.
# PPM_API_CURRENT_VERSION_* were take from driver/API_VERSION and
# PPM_SCHEMA_CURRENT_VERSION_* from driver/SCHEMA_VERSION.
# For the others, it was taken by inspecting
# falcosecurity-libs/*/CMakeLists.txt, which normally creates these
# files, but doesn't work well with the kernel-module infrastructure.
