cmd/link: use read-only mmap to back selected symbol name strings When reading symbol names from an object file, if a name does not need fixup (conversion of "". to package path), then generate a string whose backing store is in read-only memory (from an mmap of the object file), avoiding the need for an allocation. This yields a modest reduction in total linker heap use.
