[ELF] - Handle symbols with default version early.

This fixes last testcase provided in PR28414.
In short issue is next: when we had X@@Version symbol in object A,
we did not resolve it to X early. Then when in another object B
we had reference to undefined X, symbol X from archive was fetched.
Since both archive and object A contains another symbol Z, duplicate
symbol definition was triggered as a result.

Correct behavior is to use X@@Version from object A instead and do not fetch
any symbols from archive.
