I have concern on this patch.
You're modifying a basic bbclass to fix one case without finding out the
root cause.
By doing this, you're putting unnecessary restriction on the use of
commands in this bbclass. Other commands with similar dependencies could
potentially encounter the same issue in the future.
I think if you find out the root cause, you'll come up with a better
fix. This would not only resolve the current case but also prevent
similar issues.

The exception bellow occurred during
bitbake build-sysroots:do_build_target_sysroot
Re-trying the same command again can "solve" the problem, which indicates
that the problem is transient.
Transient probably means that libncurses.so.5 was not available at the
time when the useradd command was executed inside the sysroot population.
However, adding gawk-native to useradd.bbclass
DEPENDS:append:class-target does not help.
As a workaround this avoids using awk in useradd_base.bbclass.
