[ethtool PATCH 2/4] Cleanup defines and header includes to address several issues

[Alexander Duyck <alexander.h.duyck@intel.com>]

This change is meant to address several issues.  First it moves the check
for ethtool-config.h into ethtool-util.h the reason for this change is so
that any references to ethtool-util.h outside of ethtool.c will use the
correct defines for the endian types.

In addition I have pulled several headers that will be common to both
ethtool.c and rxclass.c into the ethtool-util.h header file.  I am also
centralizing several macros that will be needed across multiple files when
I implement the network flow classifier rules.
