 Remove unused oc->isImportLib (#12230)

 Summary:
 This field is never set, but it was being tested and used to decide
 whether to resolve an object or not.  This caused non-deterministic
 crashes when using the RTS linker (see #12230).

 I suspect this is not the correct fix, but putting it up so that Phyx
 can tell us what the right fix should be.

 Test Plan: validate
