Move rust-vmm/vhost code from chromiumos's third_party directory to
crosvm's one.
Note that we have crrev.com/c/3269863 for license files in Chrome OS
ebuild.
Changes:
* Copied vmm_vhost files at "7c95b4a2 rust-vmm/vhost: switch to upstream
tempfile", whose latest upstream commit is "488b3adc fix warning:
unaligned_references".
* Remove [patch.crates-io] section from its Cargo.toml.
* Add attributes to skip `clippy::bool_assert_comparison` and
`clippy::needless_borrow`, which will be fixed in following CLs.
* Update crosvm's Cargo.toml and tools/chromeos/setup_cargo
