Starting from v0.18.0, cargo-audit hangs indefinitely if Cargo.lock
does not exist. We discovered this while upgrading the container
from v26 to v28 [1], which among other things updated cargo-audit.

For the binary crates this should not be a problem, since they have
Cargo.lock committed, but for many libraries this may not be true.

If Cargo.lock is not there, we are generating one with the latest
available versions, which may not be very significant. For this and
other reasons it's now suggested that libraries also have a
Cargo.lock [2] committed (thanks Manos for pointing this out).

Note: `cargo generate-lockfile` updates Cargo.lock if it's already
there, but we don't want it, that's why we have the guard.

CI is failing since `black` suggests some reformatting.
Let's apply them.

We don't want the shell to interpret the contents of exclude_path,
but we want it all used as a single string for `--ignore-filename-regex`,
so let's put it between double quotes.

An example of failure is when we have | , as in this case:

  $ CARGO_TARGET_DIR=./cov_build cargo llvm-cov test --summary-only \
      --ignore-filename-regex crates/virtio-bindings|crates/virtio-queue/src/mock.rs \
      --workspace  --features=virtio-blk/backend-stdio
  bash: crates/virtio-queue/src/mock.rs: Permission denied
  ...
  error: failed to generate report: process didn't exit successfully: ...
  (exit status: 74)

Now that we use cargo-llvm-cov, `exclude_path` should be a regular
expression, since we are using `--ignore-filename-regex` option:

   --ignore-filename-regex <PATTERN>
       Skip source code files with file paths that match the given
       regular expression

To prevent users from separating multiple files with commas,
let's update the `exclude_path` description in the README and in
the examples.

This new version contains alsa and pipewire libraries to build

`black` suggests putting the string between single quotes so
there is no need to escape double quotes.

If we increase the coverage the message prints a negative value
as the difference from the previous value. This can be confusing
as it looks like the coverage has decreased.

For example if the value in coverage_config_x86_64.json is 73.42,
and the new coverage is 73.96 (increased), we have the following
error:

    ValueError: Current code coverage (73.96%) deviates by -0.54%
    from the previous code co...

Let's calculate the difference in reverse so that we have a
negative value if it decreases and positive otherwise.

For convenience, since the two are related directly.

Also fix a small typo while at it.

The new version reduces the size of the container by removing
unneeded pipewire dependencies and adds dbus.
This is needed to test vhost-device-sound.
