[bug#32739] Fix python-pyudev and solaar.

Dear Guix,

When installing solaar:

$ guix package -i solaar

And then running it, I get:

$ solaar
missing required package 'python-pyudev'

Now, 'python-pyudev' is already a dependency of that package, but when
loading pyudev in python, we get:

$ python3
Python 3.6.5 (default, Jan  1 1970, 00:00:01) 
[GCC 5.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyudev
...
ModuleNotFoundError: No module named 'six'

Therefore, I think 'python-pyudev' is missing a dependency for
'python-six'.

In the following patch I added this dependency to python-pyudev, after
which “import pyudev” works, and solaar starts.

Kind regards,
Roel Janssen
