Nix.pm: readNixFile: pass «--experimental-features nix-command» 
Declarative jobsets were broken by the Nix update, causing
nix cat-file to break silently.

This commit restores declarative jobsets, based on top of a commit
making it easier to see what broke.

hydra-evaluator: add a 'ONE_AT_A_TIME' evaluator style 
In the past, jobsets which are automatically evaluated are evaluated
regularly, on a schedule. This schedule means a new evaluation is
created every checkInterval seconds (assuming something changed.)

This model works well for architectures where our build farm can
easily keep up with demand.

This commit adds a new type of evaluation, called ONE_AT_A_TIME, which
only schedules a new evaluation if the previous evaluation of the
jobset has no unfinished builds.

This model of evaluation lets us have 'low-tier' architectures.

For example, we could now have a jobset for ARMv7l builds, where
the buildfarm only has a single, underpowered ARMv7l builder.
Configuring that jobset as ONE_AT_A_TIME will create an evaluation
and then won't schedule another evaluation until every job of
the existing evaluation is complete.

This way, the cache will have a complete collection of pre-built
software for some commits, but the underpowered architecture will
never become backlogged in ancient revisions.

hydra.sql: add an index for slow queries in production

Jobsets: add a SERIAL, unique, non-null id column 
A postgresql column which is non-null and unique is treated with
the same optimisations as a primary key, so we have no need to
try and recreate the `id` as the primary key.

No read paths are impacted by this change, and the database will
automatically create an ID for each insert. Thus, no code needs to
change.
