templates/Makefile.in: Improve the target management.

templates/Makefile.in:
- Fix a bug:
	Transform templates/Makefile in an actual template Makefile.in leaving less room for path inconsistencies.
- Fix a bug. Remove tmp-networkcached-related commands.

templates/buildout*.in:
- Fix a bug:
	Add the extends-cache and download-cache variables.

build-scripts/template_stage.sh:
	Add support for the new templates/Makefile.in

build-scripts/obs.sh: Fix a bug. Save the path of the local BUILD_DIRECTORY so that it can be replaced in the relevant files by the right path in OBS' VM.

dependencies.txt lists the dependencies required by the project.

Various fixes. Add OBS stage.
- Remove the top-level Makefile of the archive.
- Rename directories.
- Send directly tarballs/$SOFTWARE.
- Build from tarballs/$SOFTWARE/Makefile.
- Rename variables for clarity.
- Add obs.sh and clean_obs.sh.

- remove the networkcached support from build_tree.sh and clean_build_tree.sh
- remove the networkcached support from template_stage.sh bootstrap_buildout.sh
- remove cache_creation.sh and clean_cache_creation.sh

The scripts do everything until the first run of buildout (actual run, not just bootstraping).

See merge request nexedi/slapos.package!161

It has more chances to exist than /usr/bin/python executable

This commit also simplifies the preparation of the cache for OBS compilation.

The slapos-node package can be built in any Linux distribution (old or
new).

WARNING: Do not use PYTHON make variable since it messes up with compilation. Instead
use SLAPOS_BOOTSTRAP_SYSTEM_PYTHON which explains the idea of the variable
and does not overrides make's PYTHON variable in other places.

also do not check for invalid certificate in slapos.cfg anymore. It's
been more than 3 years that the certificate is invalid. All our machines
are updated.
