Add O_CLOEXEC to open calls.
This prevents file descriptors from leaking to child processes.
When compiled for older (pre-2.6.23) kernels which lack support for
O_CLOEXEC there is no change in behavior. With newer kernels, child
processes will no longer inherit leveldb's file handles, which
reduces the changes of accidentally corrupting the database.
Fixes https://github.com/google/leveldb/issues/623
