[llvm-objcopy][NFC] Consistenly use two dashes for flags in tests.

Summary:
As pointed out in D53667, our use of hyphens in flags can be inconsistent, mixing `-` with `--`. This change makes all long style flags use `--`.

Automatically changed via:

```
find test/tools/llvm-objcopy/ELF -type f | xargs sed -i 's/ -\([a-zA-Z]\{3\}\)/ --\1/g'
```

Two false positives were manually fixed/reverted.
