grub-core/genmoddep.awk: Ensure output is deterministic

The output in moddep.lst generated from syminfo.lst using genmoddep.awk is not deterministic since the order of the dependencies on each line can vary depending on how awk sorts the values in the array. Be deterministic in the output by sorting the dependencies on each line. Signed-off-by: Alexander Kanavin <[email protected]> Reviewed-by: Daniel Kiper <[email protected]>
