Use code from the distro package to improve linux distro detection. (#1629)

Browse source 
* Use code from the `distro` package to improve linux distro detection.

Various issues [1] [2] with the platform.linux_distribution function led
to the function being deprecated in python 3.4. The pipi package distro
[3] contains compatible improved code that better tracks current methods
for identifying linux distributions (see, for example, [4],[5]).
