feat(besadii): Trigger separate builds for build target sets r/1092

In CL/570 we split up the build targets into different buckets, with
the idea that this should help us avoid the disk space issues on
Sourcehut.

This commit changes Besadii to read the list of target sets from a
file and trigger a separate build for each one of them.
