The QTls OpenSSL backend on Unix should ignore any broken symlinks encountered rather than attempting to add the empty certificate path generated after path canonicalization to the list of trusted system certificates. Current Qt code rejects such empty paths due to using `QSslCertificate::fromFile`, but Qt 6.9- instead used `QSslCertificate::fromPath` which (before Qt 6.9.2) used to interpret an empty path to mean “add everything below the current working directory as potential certificate”! On all newer versions this only avoids unnecessarily adding an empty path to the list of certificates.
