[llvm-objdump tests] Copy the inputs of tests closer to tests.

[krasimir]

Summary

Tests under tools/llvm-objdump should not use inputs from Object. Copied the
required inputs and aligned the new tests to be more consistent with the existing
tests in this respect.

@davide I think this change makes sense. I'll accept this to unbreak our internal build. Let us know if you have any concern.
