Files in $element/environment.d are meant to be sourced, so drop
the executable bit. Moreover, drop the executable bit from a couple
of other scripts that are either meant to be sourced or simply because
they are configuration files.

This patch solves three issues with Debian packaging / apt:
o When building 'testing' only default apt sources is
included - backports, updates and security are skipped because they
do not exists.
o The default release for Debian was `unstable`: this is now fixed to
`stable`.
o Starting a Debian Stretch VM that was build with diskimage-builder
does not work, because some mandatory packages are missing.
This patch fixes this problem: it adds the mandatory packages and
the test case.
