const variables are put into the text segment, so !KALLSYMS_ALL includes them into the kallsyms section. Remove them to make the kallsyms smaller. This also avoids some problems with LTO. The way LTO generates the first pass kallsyms cannot handle variables currently, so if we don't filter them out the first and second level pass differ too much.
