ExternalProject: Ensure svn --trust-server-cert has dependent options
If the --trust-server-cert option is given to svn without the --non-interactive option, the command fails with an error. Previously, --non-interactive was always added, but !7248 (merged) changed the behavior to only add it if the relevant USES_TERMINAL_... option was set to true.
Fixes: #25197 (closed)
