FIX: Dockerfile typo causing it to fail

Wow, I had no idea anyone paid attention to this old branch. I gave up on building Alpine (or other distro) images for lack of time. Note that this branch hasn't been touched in six years.

I mean that's definitely a bug, but you using this branch?

[benjamin-chang]

I don't. The current image has a couple CVE's and I was looking for an alternative.

• libtommath:1.2.0-6/CVE-2023-36328
• zlib:1:1.2.13.dfsg-1/CVE-2023-45853

If I weren't able to fix it inline on github, I would have just ignored it.

Ah. Well it's probably time to update the base.
