[libvirt PATCH v3 2/3] gitlab-ci.yml: Convert only/except to the rules syntax

[Erik Skultety <eskultet@xxxxxxxxxx>]

'rules' syntax replaces the only/except syntax with which it is
mutually exclusive. In some cases the 'rules' syntax is more readable
than the 'only/except' equivalent, in some cases it is not.
The idea behind this conversion is to introduce an explicit env variable
controlling the 'allow_failure' attribute which would then be attached
to a broken build job which would in turn result in a soft failure.
Such behaviour is not possible to achieve with the older 'only/except'
syntax.
