Add systemd service files equivalent to xdebian-edu-firstboot init script
The init script performs two tasks on the first boot after installation.
Firstly, it starts the run-at-firstboot script from debian-edu-config.
Secondly, it runs tests via the debian-edu-test-install script provided by
debian-edu-config if requested by the user via the testinstall argument on the
kernel command line. Any errors found will be mailed to the first user and
success or failure will be signaled through a graphical dialog on top of the
display manager.
Factor out the test runner into a separate script debian-edu-testsuite. This
script is then run by the xdebian-edu-firstboot sysvinit script. Create two
systemd service files, one which runs the run-at-firstboot script and another
one for running debian-edu-testsuite.
Remove unsupported update-rc.d options.
