Subject: [PATCH] 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.

Also, the output of the SOURCES lines in grub-core/Makefile.core.am, generated
from grub-core/Makefile.core.def with gentpl.py is not deterministic due to
missing sorting of the list used to generate it. Add such a sort.

Also ensure the generated unidata.c file is deterministic by sorting the
keys of the dict.
