Install yq without Ansible (#1608)

Resolves #1595

As part of our continuing effort to eliminate Ansible from our install
process, this installs yq from within the bundle installer rather than
during Ansible.

This is a slight implementation change in that we no longer download the
yq binary at install time and instead pre-download it and include it in
the TinyPilot bundle. This is preferable, as it does more work in the
packaging stage and less work on user devices, though it does increase
the size of our bundles by a few megabytes.

While we're here, we're also upgrading to the latest version of yq, so
we're upgrading from `v4.30.6` to `v4.35.1`.

### Manual tests

For expediency, I tested builds that combined:

* #1605
* #1606 
* #1608

For the manual tests, I verified:

* Video works under MJPEG and H.264
* Changing video settings works

In these environments:

- [x] Pro Voyager build
- [x] Community bundle on top of bare Raspbian system
- [x] Community bundle on top of bare Raspbian system with TC358743
enabled

### Peer tests

To test this bundle (which combines the stack of three PRs mentioned
above), run:

```bash
curl \
  --silent \
  --show-error \
  --location \

  sudo bash -s -- \
