gitlab-ci.yml: Merge one of the coroutine jobs with the tcg-disabled job

Our gitlab-ci got quite slow in the past weeks, due to the immense amount
of jobs that we have, so we should try to reduce the number of jobs.
Since we already have a job that builds without TCG, we can merge
one of the "build-coroutine" jobs with it to get rid of at least one
job.
