The old tarball was not removed correctly

These crontabs were using execfile which has been removed on python 3.

fixup for 203927d9

The directory must be correct in slapos.spec.

This script had #!/opt/slapos/parts/python2.7/bin/python2.7 which we
no longer ship.

This might be the reason why the test fail with an error like this in the log

    TASK [standalone-shared : Check ERP5 state] ************************************
    fatal: [127.0.0.1]: FAILED! => {"changed": true, "cmd": "/usr/local/bin/erp5-show -s", "delta": "0:00:00.003072", "end": "2022-09-01 22:49:43.877821", "failed": true, "rc": 127, "start": "2022-09-01 22:49:43.874749", "stderr": "/bin/sh: 1: /usr/local/bin/erp5-show: not found", "stdout": "", "stdout_lines": [], "warnings": []}

1.0.248 is the most recent version that is in binary cache

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.
