  [ORC] Fix materialization of weak local symbols

We were adding all defined weak symbols to the materialization
responsibility, but local symbols will not be in the symbol table, so it
failed to materialize due to the "missing" symbol.

Local weak symbols come up in practice when using `ld -r` with a hidden
weak symbol.
