Given GitLab moves away from using the term build, everywhere, also the
CI variables are being renamed.

For now, both `CI_BUILD_X` and `CI_JOB_X` are supported, with the same
values. However, in about 3 months, support will be dropped.

Rather than using a separate `ghost` state. This lets us have the benefits of
both ghost and blocked users (ghost: true, state: blocked) without having to
rewrite a number of queries to include cases for `state: ghost`.

and remove the old one which we don't really need.
