test-lib-functions.sh: remove misleading comment on test_seq
 
We never used the "letters" form since we came up with "test_seq" to
replace use of non-portable "seq" in our test script, which we
introduced it at d17cf5f3 (tests: Introduce test_seq, 2012-08-04).

We use this helper to either iterate for N times (i.e. the values on
the lines do not even matter), or just to get N distinct strings
(i.e. the values on the lines themselves do not really matter, but
we care that they are different from each other and reproducible).

Stop promising that we may allow using "letters"; this would open an
easier reimplementation that does not rely on $PERL, if somebody
later wants to.
