LTO: Properly check wrapper symbol
Add wrapper_symbol to bfd_link_hash_entry and set it to true for wrapper
symbol. Set wrap_status to wrapper if wrapper_symbol is true in LTO.
Note: Calling unwrap_hash_lookup to check for the wrapper symbol works
only when there is a definition for the wrapped symbol since references
to the wrapped symbol have been redirected to the wrapper symbol.
