  [ELF] Mention section name for STT_SECTION in reportRangeError()

D73518 mentioned non-STT_SECTION symbol names. This patch extends the code to
handle STT_SECTION symbols, where we report the section name.
This change helps at least the following cases with very little code.

* Whether a out-of-range relocation is due to code or data.
* For a relocation in .debug_info, which referenced `.debug_*` section (due to DWARF32 limitation) causes the problem.
