[llvm-readobj] - Merge gnu-symbols.test to symbols.test and cleanup.
This cleans up and merges `gnu-symbols.test` to `symbols.test`. Initially `gnu-symbols.test` tested the following things: 1) How symbols are printed in GNU style. It does not make sense to have a separate file for such tests. 2) It tried to test proc-specific symbol indexes. The test was incomplete and also we already have `symbol-shndx.test` for that, so this part was removed. 3) It tested `--dyn-symbols` and `--symbols` correlation. All following cases were moved to `symbols.test`: a) That `--dyn-symbols` does not trigger showing regular symbols.. b) That `--symbols` triggers `--dyn-symbols` implicitly. c) That `--dyn-symbols` and `--symbols` works fine together.
