CI: fix name of jobs

[Kobzol]

There is a difference between the image (the Dockerfile), the name of the job (which determines also its properties) and the full_name, which includes the auto/try/pr prefix.

Missed this in #134898.

ERROR: failed to download llvm from ci

    HELP: There could be two reasons behind this:
        1) The host triple is not supported for `download-ci-llvm`.
        2) Old builds get deleted after a certain time.
    HELP: In either case, disable `download-ci-llvm` in your config.toml:
    [llvm]
    download-ci-llvm = false
    
Build completed unsuccessfully in 0:00:22

An S3 archive has to be copied before CI can progress.

This change is reasonably straightforward and makes sense to me, so I think it is okay to merge.
