Override host OS dlclose() with a NOP.

This NOP implementation is needed as workaround for a known limitation in LSAN (leak sanitizer) that if dlcose is called before performing the leak check, “<unknown module>” is reported in the stack traces during the leak check and these can not be suppressed, see https://github.com/google/sanitizers/issues/89 for more info.
