It appears that the LLTrans machinery, or at least the way it's used in this
program, is buggy: linux-updater.bin has been crashing. Tracebacks and
experimentation identify LLTrans as the culprit, so replace it with baked-in
string constants copied from strings.xml. (linux-updater.bin was already
producing English-only messages because the update_install shell script that
calls it was specifically passing the English version of strings.xml.)
