Erik Bray bf12e4ecca wolfcrypt Python: work around minor issue in Random.__del__ 
During interpreter shutdown, depending on the order in which things happen, a module can be unloaded before all instances of classes defined in that module are garbage collected.

In particular, this means that any global variables (including imported modules) become `None` by the time the instances `__del__` is called, resulting in
```
AttributeError: 'NoneType' object has no attribute 'wc_FreeRng'
```
being displayed while the process exits.  This can be avoided simply by catching and ignoring the `AttributeError` in this case, since the process is shutting down anyways.

Erik Bray e96a720f04 Fixes a serious bug in Random.byte 
Python's bytecode compiler has a peephole optimizer which, among other things, can recognize constant expressions and replace them with a constant.

In `Random.byte` the expression `t2b('\0')` is recognized as a constant and is replaced with a single constant compiled into the function's bytecode.

This means that every time you run `Random.byte`, rather than creating a new `str` object (or `bytes` in Python 3) it's reusing the same one each time, and `wc_RNG_GenerateByte` is writing right into that constant object's buffer; hence the following behavior:

```
In [55]: rng = Random()

In [56]: a = rng.byte()

In [57]: a
Out[57]: "'"

In [58]: rng.byte()
Out[58]: '\x11'

In [59]: a
Out[59]: '\x11'

In [60]: rng.byte()
Out[60]: '\x16'

In [61]: a
Out[61]: '\x16'

In [62]: rng.byte.__func__.__code__.co_consts
Out[62]:
('\n        Generate and return a random byte.\n        ',
 '\x16',
 0,
 'RNG generate byte error (%d)')

In [63]: rng.byte()
Out[63]: '\xad'

In [64]: rng.byte.__func__.__code__.co_consts
Out[64]:
('\n        Generate and return a random byte.\n        ',
 '\xad',
 0,
 'RNG generate byte error (%d)')
```

`Random.bytes` does not necessarily have this problem since its result buffer is not a constant expression, though I feel like it could also in principle be affected if the string were interned (though I couldn't produce such a result). Nevertheless, it doesn't seem like a good idea to be updating `str` objects' buffers directly.
