Parse and propagate the name of the kernel relocation symbol (#675)

* Extend ObjTool to propagate the original mapping name.

For kernel mappings, the original mapping file name (not the name under
which we found the actual symbols file) is necessary to correctly
compute the kernel relocation offset. Preserve that name through
ObjTool.

Tested: unit.

* Preserve DSO name at decode time.

* Use DSO consistently instead of baseName

* Handle empty File correctly.

* Clarify merging / mapping semantics for DSO field.

* Switch extra field from DSO to a more narrow KernelRelocationOffset.

* Wording.
