d1680b9ff9 tests: streamline module names to unit_tests
This better aligns with the rest of the code and makes it clearer
that these tests can run "as is" in a normal hosted environments
without the special test environment.

ea4693a091 misc: Fix clippy error from beta compiler
Rust has a new way of constructing other error and clippy complains if
we are still using the older way to construct error message. Thus,
migrate to the new approach suggested by the clippy.

Warning from beta compiler:

error: this can be `std::io::Error::other(_)`

297236a7c0 misc: Eliminate use of assert!((...).is_ok())
Asserting on .is_ok()/.is_err() leads to hard to debug failures (as if
the test fails, it will only say "assertion failed: false". We replace
these with `.unwrap()`, which also prints the exact error variant that
was unexpectedly encountered (we can to this these days thanks to
efforts to implement Display and Debug for our error types). If the
assert!((...).is_ok()) was followed by an .unwrap() anyway, we just drop
the assert.

Inspired by and quoted from @roypat.

c1be41bfbf net_util: Replace use of rand crate with libc::getrandom()
The rand crate provides a full cross platform true cryptographic random
number implementation. As such it brings it lots of othe dependencies
and increases our binary size and compile time. This is excessive for
generating a MAC address.

From the cargo tree output:

│   │   │   ├── libc v0.2.86
│   │   │   ├── rand_chacha v0.3.0

53f5295454 network: Add virtio-net dependencies
The newly added virtio-net implementation needs to interact with TAP
interfaces and MAC addresses, which is the reason why it is easier
to rely on existing packages net_util and net_gen.

One more thing, both net_util and net_gen could be trimmed down,
based on using only the things we need from cloud-hypervisor.

Both net_util, net_gen and sys_util are based on Firecracker
