Are you saying that this line is failing:
is_on_target_path useradd PROGRAM_USERADD
?

According to the Linux File System Hierarchy Standard, useradd is supposed
to be located in /usr/sbin.  See https://refspecs.linuxfoundation.org/FHS_3.0/fhs-3.0.pdf
So I think it would be acceptable to specify the full path: /usr/sbin/useradd.

A bit more robust is to use the value obtained from is_on_target (or is_on_target_path).

If /usr/sbin is not in the ssh interactive login PATH, then try this:
is_on_target useradd PROGRAM_USERADD /bin:/sbin:/usr/bin:/usr/sbin

In the echo statement that creates run-test.sh, you should be able to
use
    $PROGRAM_USERADD fuego_test_special;
instead of
    useradd fuego_test_special

As an aside, do we want the $(realpath /lib/libBrlkenLocale.so.1) 
variable substitution to happen on the host at run-test.sh creation
time, or on the target at run-test.sh execution time.  It looks to me
like it's getting substituted on host, but should rather be substituted
on target.  To do this, I think the $ would need to be escaped in this
set of echo lines.

I hope this is useful.
