rG5f6ff716417a: [llvm-readobj][test] - Add a check for --dyn-syms.
Summary

We have the -dyn-symbols option. It has a --dyn-syms alias
that is not tested in llvm-readobj tests currently.

There is a Object/readobj-elf-versioning.test where it is used,
but I am removing it in D73163. And also it is not the
right place to test it anyways.
