[SPARK-16077] [PYSPARK] catch the exception from pickle.whichmodule()
## What changes were proposed in this pull request?
In the case that we don't know which module a object came from, will call pickle.whichmodule() to go throught all the loaded modules to find the object, which could fail because some modules, for example, six, see https://bitbucket.org/gutworth/six/issues/63/importing-six-breaks-pickling
We should ignore the exception here, use `__main__` as the module name (it means we can't find the module).
## How was this patch tested?
Manual tested. Can't have a unit test for this.
