leveldb: Require C++11.

This CL switches the public headers to C++11 default and deleted constructors, and adds override to the relevant leveldb::EnvWrapper methods. This should be a good test for C++11 compiler support.

Once this CL settles, the rest of the codebase can be safely modernized to C++11.
