To ensure dependencies don't accidentally get updated, their versions are
fixed using the equals constraint. The Cargo.lock file is also checked in
so that the registry won't need to be downloaded by cargo.
These changes are needed so that the crosvm ebuild will not need to
download anything outside of its list of source packages.
