Makefile: fixes to bugs that break diffconfig and applydiffconfig

Browse Source 
This patch resolves the following bugs that break the targets `diffconfig`
and `applydiffconfig`:

 - Comments after variable definitions cause the varaible to contain
   unintended trailing whitespaces.

 - HV_CONFIG_XML is no longer defined; it is now HV_SCENARIO_XML.

 - '*.asl' files are also generated and should be involved when comparing
   the generated configuration files.

 - Strings between diacritic marks (`) are intepreted as shell commands
   even they are part of informative messages.

 - HV_DIFFCONFIG_LIST should not contain duplicated lines.

Tracked-On: #5772
