don't correlate __verbose statics

The __verbose section stores several static local structs named
"descriptor".  These structs contain information related to dynamic
debugging printks and are specific to the patched object, so they
shouldn't be correlated with their base object counterparts.

Fixes the following error:

    kpatch_correlate_static_local_variables: 830: static local variable descriptor.49967 not used
detect .rodata.* bundled sections

Detect .rodata.* bundled sections so that .rodata.__func__.* relocation
references can be converted to refer to their corresponding object
symbols.

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
