gh-150922: Fix test_cmd libedit assertion in
test_bang_completion_without_do_shell (GH-156623)
GNU readline retypes the full completed word after tab completion, but
libedit redraws only the untyped suffix following a cursor-forward
escape sequence. Assert on the common suffix ('ello') instead of the
literal 'hello' bytes so the test passes on both backends.
(cherry picked from commit 0b4c7da5c401154af7b7cb89a6467365cadc2653)
