Build rustdoc for run-make tests, not just run-make-fulldeps

Rustdoc almost never needs a full stage 2 compiler, and requiring
rustdoc tests to be in run-make-fulldeps adds a lot of compile time for
no reason.

This is the same change from rust-lang#81197, but separated into its own PR. I ran into this again today while working on rust-lang/docs.rs#1302.
