That now fails for cases where the USERADD_PARAM ends in trailing white
space after the last valid opts. The reason is that the 'if test "x
$opts" = "x$remaining"; then break; fi' check does not get triggered
anymore, because $remaining has the trailing white space whereas "$opts"
does not.

I'm not sure what the best approach is in this case. Perhaps also strip
trailing whitespace from all assignments to $remaining?

The case were we see this is:
USERADD_PARAM_iot-rest-api-server="--system --home /var/lib/empty --no-create-home --shell /bin/false --gid restful restful "

The build then hangs because the useradd preinst loops forever.
