Hi.

With this contribution, I bumped sysdig and falcosecurity-libs.
Sadly, I am not fully satisfied with the result, hence the fact I marked it as
RFC because I would like to get your feedback to make it better.

First of all, sysdig builds and runs:
Welcome to Buildroot
buildroot login: root
# sysdig --version
sysdig version 0.31.4
# sysdig | head
scap: loading out-of-tree module taints kernel.
scap: driver loading, scap
scap: adding new consumer (____ptrval____)
scap: initializing ring buffer for CPU 0
scap: CPU buffer initialized, size=8388608
26 15:12:28.226519423 0 sysdig (108) > switch next=0 pgft_maj=10 pgft_min=1348 vm_size=47288 vm_rss=19408 vm_swap=0
27 15:12:28.227409149 0 <NA> (0) > switch next=13 pgft_maj=0 pgft_min=0 vm_size=0 vm_rss=0 vm_swap=0
...

Nonetheless, I had to increase the minimal size of the image as libsinsp.a is
quite big:
# du -sh /sysdig/libsinsp.a
171.4M  /sysdig/libsinsp.a
I am not forcefully sure where this library is used, I will investigate and
maybe we can run everything without it.
This /sysdig directory is installed by sysdig Cmake due to the following being
present in cmake_install.cmake:
if(CMAKE_INSTALL_COMPONENT STREQUAL "scap" OR NOT CMAKE_INSTALL_COMPONENT)
  list(APPEND CMAKE_ABSOLUTE_DESTINATION_FILES
   "/sysdig/driver/")
  if(CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION)
    message(WARNING "ABSOLUTE path INSTALL DESTINATION : ${CMAKE_ABSOLUTE_DESTINATION_FILES}")
  endif()
  if(CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION)
    message(FATAL_ERROR "ABSOLUTE path INSTALL DESTINATION forbidden (by caller): ${CMAKE_ABSOLUTE_DESTINATION_FILES}")
  endif()
  file(INSTALL DESTINATION "/sysdig/driver" TYPE DIRECTORY FILES "/home/francis-buildroot/buildroot/output/build/sysdig-0.31.4/buildroot-build/driver/src/" FILES_MATCHING>
endif()

Changes since:
 v1:
  * Removed everything regarding VALIJSON in sysdig.mk.
  * Bumped first falcosecurity-libs to avoid problem when building it.
  * Added runtime test for sysdig.
 v2:
  * Automatically got value for API_VERSION and SCHEMA_VERSION.
  * Added DEPS as sysdig dependencies.

Francis Laniel (3):
  package/falcosecurity-libs: bump to version 0.10.5
  package/sysdig: bump to version 0.31.4
  support/testing/package: add new test for sysdig
