[llvm-readobj/elf] - Merge mips-got-overlapped.test to mips-got.test and refine testing.
The `mips-got-overlapped.test` was introduced in D16968 and its intention is to check that when there is an empty section at the same address as `.got`, then we are able to locate `.got` and dump it. The issue is that this test does not test llvm-readelf and uses a precompiled object. This path starts using YAML instead and merges mips-got-overlapped.test to mips-got.test.
