Bug#1121778: install_packages: will not load package_config file when class contains dash

[Thomas Lange]

In FAI 6.5 this was fixed
using this change:

-@clvar =  map { $_,1 }  grep { s/-/Ö/g } @classes;
+@clvar =  map { $_,1 }  grep { s/-/Ö/g;1 } @classes;


Can you please confirm that this also works for you.
