See merge request nexedi/slapos.package!166

fixup for 203927d9

The old tarball was not removed correctly

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

Switch to `slapos console script.py` syntax which was introduced in
slapos 1.4.5

See merge request nexedi/slapos.package!167

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.
