fix: refix sd-local display bug

[yakanechi]

Context

#465 was insufficient so the sd-local user step still included the output of the sd-setup-launcher step.

The reason is that the output of the sd-setup-laucher command changes depending on the job image.
In some images, the output of echo ; was not empty and contained a prompt characters such as $ and #, which could cause the loop to be stuck.

Objective

The goal is that the sd-local user step does not include the output of the sd-setup-launcher step.

As a result of the fixes, it now works as follows.

Before

sd-setup-launcher: set -e && export PATH=${PATH}:/opt/sd:/usr/sd/bin:/usr/sd-static/bin && finish() { EXITCODE=$?; tmpfile=/tmp/env_tmp; exportfile=/tmp/env_export; export -p | grep -vi "PS1=" > $tmpfile && mv -f $tmpfile $exportfile; echo $SD_STEP_ID $EXITCODE; } && trap finish ABRT EXIT;
sd-setup-launcher: 
echo: $ echo "Hello world"
echo: <port; export -p | grep -vi "PS1=" > $tmpfile && mv -f $tmpfile $exportfile; echo $SD_STEP_ID $EXITCODE; } && trap finish ABRT EXIT;
echo: 
echo: Hello world
echo: 

After

sd-setup-launcher: set -e && export PATH=${PATH}:/opt/sd:/usr/sd/bin:/usr/sd-static/bin && finish() { EXITCODE=$?; tmpfile=/tmp/env_tmp; exportfile=/tmp/env_export; export -p | grep -vi "PS1=" > $tmpfile && mv -f $tmpfile $exportfile; echo $SD_STEP_ID $EXITCODE; } && trap finish ABRT EXIT;
sd-setup-launcher: echo ;
sd-setup-launcher: <port; export -p | grep -vi "PS1=" > $tmpfile && mv -f $tmpfile $exportfile; echo $SD_STEP_ID $EXITCODE; } && trap finish ABRT EXIT;
sd-setup-launcher: echo ;
sd-setup-launcher: 
echo: $ echo "Hello world"
echo: Hello world
echo:
