[ci:skip-build]: already built successfully in CI
Ideally tqftpserv should be started before rmtfs. This is because rmtfs
is currently responsible for starting the modem, and it's best for
performance if all the services needed by the modem are already up.
Also change "want" -> "use" for consistency with rmtfs. The difference
between "want" and "use" is that "want" just triggers starting of the
other service, while "use" also ensures that the other service starts
successfully.
