  [ELF] Optimize parseSymbolVersion

We can just scan objectFiles and sharedFiles that have versioned symbols
to skip scanning the global symtab. While we won't suggest __wrap_foo
for undefined __wrap_foo at v1 when --wrap=foo at v1 is specified
(internalFile isn't scanned), this edge case difference is acceptable.
