television: add extraPackages option with default dependencies

Add an extraPackages option to the television module that wraps the `tv`
binary with additional packages in PATH. Defaults to fd, bat, and ripgrep
which are the dependencies required by television's default channels.

Existing tests updated to set extraPackages = [ ] since they test config
generation, not binary wrapping.
