Adds minimal set of dependencies required
for the "foundation" application to build
and initialize:
- SAMGR (distributed services manager + headers)
- SAFWK (project containing sources of the foundation app)

Note:  Debugging output is enabled by default on SAFWK
Note2: Currently SAMGR can include OS adapter only for
       Linux (posix) or uC (cmsis). If LiteOS or other
       system is going to be used, please modify
       samgr_git.bb's TARGET_ADAPTER accordingly.
