build: install diffutils in test container image

Depending on the local changes, running 'make containerized-test' fails
with an error like:

    level=error msg="Running error: gofmt: error computing diff: exec: \"diff\": executable file not found in $PATH"

Installing the diffutils package makes sure 'go fmt' finds the
executable.
