[services] Add curl to the base image

Summary:
Depends on D4858

I added curl to the base image since it is needed to install rust.

The reason I didn't add rust right away to the base image is that we'll be using rust in the backup and tunnelbroker which makes it redundant in the blob service.

Test Plan: services build
