python-cryptography: Duplicate self-signed intermediates can cause exponential path-building

### Summary When resolving invalid certificate chains that include duplicate copies of self-signed certificates, the processing recursively invokes the same candidate, leading to an exponential blowup. Although the limitation that the chain depth can
