[llvm-readelf/obj][test] - Stop using precompiled binary in mips-plt.test

[grimar]

Summary

This removes the precompiled binary and rewrites test to use YAML.

After this change we'll have no more precompiled inputs in llvm-readobj/ELF/Inputs.

Not really knowing MIPS, it's probably best if @atanasyan reviews this.

What's the point of the 2>&1? There's no check that there are [no] warnings in the readobj case at least.

You're right. Placed it by mistake, I'll remove.
