kvm/test: kvm0 -> KVM0

The kvm software release was recently modified to use
slapos.cookbook:switch-softwaretype instead of the deprecated
slapos.cookbook:softwaretype.

The latter uses ConfigParser to generate
buildout-switch_softwaretype.cfg from template-*.cfg. However,
ConfigParser changes the section keys to lowercase, as shown in the
following example:

>>> from six.moves.configparser import ConfigParser
>>> from io import StringIO
>>> c = ConfigParser()
>>> c.readfp(StringIO("[FOO]\nBAR = BAZ"))
>>> s = StringIO()
>>> c.write(s)
>>> s.getvalue()
'[FOO]\nbar = BAZ\n\n'

This behavior is not present with
slapos.cookbook:switch-softwaretype.
