From: Richard Purdie <richard.pur...@linuxfoundation.org>
We're seeing reproducibility issue on the autobuilder due to changing
module dependency ordering. Add some sorting to an awk script to fix this.

+The output in moddep.lst generated from syminfo.lst using genmoddep.awk is

+Be deterministic in the output by sorting the dependencies on each line.
