CI: only make install.tools when needed

Reintroduce .install.foo targets into Makefile, and invoke
only the bare-minimum ones needed for each individual CI
step in setup_environment.sh.

Also add a retry to the golangci-lint curl, in hopes of
dealing with network flakes. And remove the -f (fail)
because it produces unhelpful logs.

Reason: saw about 25% CI flakes yesterday due to the golangci-lint
fetch, something about a timeout, and this was especially frustrating
because none of the steps actually needed lint. Quick reminder:
avoid network fetches unless absolutely necessary.

Fixes: #15892
