Remove dynamic allocation of atomic

Since #1925 building static binaries fails because of a hardcoded `dylib`.
Removing the `dylib` but still let rust search for the dependency it
will still link it.

This should still keep #1645 fixed but also fixes #2043.

I have tested this by building Vaultwarden for both dynamically linked
debian based image, and a statically linked musl/alpine based image.
But are using OpenSSL v3.x.x.
