Revert r314817 "[dwarfdump] Add -lookup option"

The test fails on Linux; see follow-up email on the llvm-commits list.

> Add the option to lookup an address in the debug information and print
> out the file, function, block and line table details.
>
> Differential revision: https://reviews.llvm.org/D38409

This also reverts the follow-up r314818:

> [test] Fix llvm-dwarfdump/cmdline.test
>
> Fixes test/tools/llvm-dwarfdump/cmdline.test
