Add missing header files for source distribution

We were not listing all of the uapi header files in ethtool_SOURCES
which prevented the proper construction of a distribution source
tarball. This is noticeable with older kernel headers where the build
would be breaking in such a way:

/storage/buildroot/output/arm64/host/bin/aarch64-linux-gcc
-DHAVE_CONFIG_H -I.  -I./uapi  -D_LARGEFILE_SOURCE
-D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Wall -Wextra
-D_POSIX_C_SOURCE=200809L -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
-D_FILE_OFFSET_BITS=64  -Os -g0 -D_FORTIFY_SOURCE=2 -std=gnu11 -c -o
netlink/rings.o netlink/rings.c
