Fix reading of binary data in read()

As per the current code, this is the behavior:

>>> with v.fopen("/abc", 'r') as f:
...     data = f.read(5)
>>> print data
<ctypes.c_char_Array_2 object at 0x7fda7d6bbb90>
>>> print data.value
hello
>>>

It's incorrect to return a ctypes internal object back to the user.

In Python 2.x, read() always returns a string. It's really upto
the consumer to decode this string into whatever encoding it was
written with.

This patch reverts parts of this old change:
