[clang][test] remove unused run overload in BoundNodesCallback

The overload that did not take the additional `ASTContext *` argument is
unnecessary when the context could simply be commented out, as it is
always passed to `run` from `VerifyMatcher::run`.
This patch removes the single-argument overload in favor of having a
single overload.
