kcminit: use KGlobalSettings::isMultiHead() instead of checking for hidden config key

Browse source 
as the comment says - there is no interface for it, there isn't one for
what KGlobalSettings::isMultiHead() checks for but it checks for
environment variable. now the klauncher KDE_MULTIHEAD environment variable
will match the global envionment variable
