[llvm-readelf][llvm-readobj][test] - Cleanup test cases for versioning sections.
Currently we have 2 tests for testing versioning sections: 1) elf-versioninfo.test 2) elf-invalid-versioning.test The first one currently checks how versioning sections are dumped + how tools dump invalid SHT_GNU_verdef section. The second despite of its name contains only tests for invalid SHT_GNU_verneed section. In this patch I`ve renamed elf-invalid-versioning.test->elf-verneed-invalid.test, and moved a few tests from elf-versioninfo.test to a new elf-verdef-invalid.test. It will help to maintain these and a new tests for broken versioning sections. Differential revision:
