fix COPY error

[dradetsky]

If you aren't using buildx, the instruction COPY *.patch . fails due to not being able to copy anything to the container.

Given that COPY . /var/www would already include any .patch files I think it better just to remove the COPY *.patch . line.

Can you please test/confirm in your environment?

[dradetsky]

@lcrilly I agree

[lcrilly]

And now we don't need the new null.patch file ;)

@lcrilly did I not delete that file in my last commit? It says I did.

Must have been my browser cache. Looks good now.
