Fix databroker cli

[vasilvas99]

Issue

The databroker-cli fails to build with the provided in the root of the cargo-workspace Cargo.lock, since this lock was generated with a Rust version newer than 1.59.0.

This leads to problems with the dependency resolution during the compilation.

Solution

Delete the repository-provided Cargo.lock, thus causing the bitbake Rust compilation tasks to re-generate it with dependencies matching the Rust version used for the build.

Result

After this fix a clean build goes through and after boot the databroker-cli can be tested:

root@qemuarm64:~# databroker-cli 
transport error
client> help
client commands:

  get             - Get a HAL property
  set             - Set a HAL property
  feed            - Set a HAL property (from vehicle side)
  connect         - Connect
  subscribe       - Subscribe to properties
  metadata        - Get datapoint metadata
  help            - You're looking at it
  quit            - Quit the demo

client> quit
Bye bye!
