keyd: Verify current udevd process is supervised by runit
https://github.com/void-linux/void-packages/pull/38467

Description:
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **YES**

This PR adds a check to the runit service for `keyd`. Sometimes, when starting the `keyd` service, the keyboard can become unresponsive. This was the result of the `udevd` process being replaced while `keyd` was launching. See [here](https://github.com/rvaiya/keyd/issues/263) for more details.
