ci: Improve OpenBSD core dump backtrace handling.
Since OpenBSD core dumps do not embed executable paths, the script now
searches for the corresponding binary manually within the specified
directory before invoking LLDB. This is imperfect but should find the
right executable in practice, as needed for meaningful backtraces.
