[LLD][ELF] --wrap: __real_foo references should trigger archive extraction for foo

A reference to __real_foo should trigger archive extraction of the input file that defines foo, otherwise a link using --wrap=foo might fail to link with an undefined reference to foo.
This matches bfd linker behaviour.
