runtime: fix TestGdbAutotmpTypes on gdb version 15

On Arch Linux with gdb version 15.1, the test for TestGdbAutotmpTypes print
the following output,

----

In the back trace for "File runtime", each output lines does not end with
";" anymore, while in test we check the string with it.

While at it, print the expected string with "%q" instead of "%s" for
better error message.

Fixes #67089
