Documentation/sphinx: fix kernel-doc decode for non-utf-8 locale

On python3, Popen() universal_newlines=True converts the subprocess
stdout to unicode text using a codec based on user preferences. Given
LANG indicating ascii and utf-8 stdout from the subprocess, you'd get:

WARNING: kernel-doc '../scripts/kernel-doc -rst -enable-lineno
../drivers/media/dvb-core/demux.h' processing failed with: 'ascii' codec can't
decode byte 0xe2 in position 6368: ordinal not in range(128)

Fix this by dropping universal_newlines=True and replacing the implicit
LANG specific decode with an explicit utf-8 decode. This also gets rid
of the annoying conditional code for python 2 vs. 3.
