Add comments deleted by YCP Killer

When this module was translated from YCP to Ruby using YCP Killer, two
comments were lost because of a bug in yast2-core. This bug has since
been fixed (in yast2-core 3.0.1). After the fix I re-translated this
module using fixed yast2-core and made a diff against the original
translation result. This commit applies this diff, restoring the lost
comments.
