RUSTSEC-2020-0129: kekbit: ShmWriter allows sending non-Send type across threads

Description

Affected versions of this crate implement Send for ShmWriter<H> without requiring H: Send. This allows users to send H: !Send to other threads, which can potentially lead to data races and undefined behavior.
