compare static prefixes, don't correlate __verbose symbols

Fixes the following error:

    kpatch_correlate_static_local_variables: 865: expected bundled section for descriptor.49967
detect .rodata.* bundled sections

Fixes the following error:

    kpatch_correlate_static_local_variables: 830: static local variable __func__.49968 not used
compare __func__ references by value

Fixes the following error:

    kpatch_correlate_static_local_variables: 850: found another static local variable matching __func__.49968 in patched .rela__verbose
don't replace section references with symbols for debug sections

Fixes a seg fault in kpatch_create_dynamic_rela_sections when processing
the relas for the .debug_info section, when it tries to reference an
unincluded symbol from the __verbose section.
