tests: fix spurious failure of txinfo21.test on FreeBSD

* tests/txinfo21.test: Use the `is_newest' subroutine instead of
the `ls -t' hack to to determine whether a file has been updated.
This is required because at least FreeBSD `ls' do not sort files
with the same timestamp in alphabetical order when using the `-t'
option.
