[Buildroot] [PATCH] ethtool: Allow enabling/disabling pretty printing

[Florian Fainelli <f.fainelli@gmail.com>]

Ethtool has a configure script option allowing the enabling or disabling of
pretty printing for drivers, SFP modules etc which can save a significant
amount of bytes on the root filesystem. Allow selecting that, and turn it on by
default (like ethtool's configure script).
