chunked body autests: avoid UUID colision (#11843)

The ATS via header string contains a UUID which is a set of hex values.
Since some of the chunked encoding tests used a chunked body of abc,
this would sometimes coincidentally cause a failure when the autest
found abc, not from the body, but from the UUID. This avoids that by
including non-hex values in the test body.

Fixes #11841

(cherry picked from commit 13abab6)
