[llvm-objdump] - Restore a piece of code removed by mistake in r352366.

Seems when committed the r352366
("[llvm-objdump] - Print LMAs when dumping section headers.")
I resolved merge conflict incorrectly and removed this piece by mistake.

Bots did not catch this yet, seems they are slow today,
but the `X86/adjust-vma.test` test case fails locally for me without that.
