Subject: [PATCH 15/26] kallsyms: Annotate static information into meminspect

Annotate vital static information into meminspect:
 - kallsysms_num_syms
 - kallsyms_relative_base
 - kallsysms_offsets
 - kallsysms_names
 - kallsyms_token_table
 - kallsyms_token_index
 - kallsyms_markers
 - kallsyms_seqs_of_names

Information on these variables is stored into inspection table.
