This is the tail of the Builds table on that machine:

So the problem is that we’re trying to insert one of these again, which
fails because we already have it under this primary key.

This is because the curl-7.55.0 package ends up twice in the list of
jobs: once as a replacement for curl-7.53.0, and once because the
curl-7.55.0 is itself a public variable.

Commit 7d4d6c13f46f2a307883226789d6aa503e2d7081 in guix-maintenance.git
works around that.

The proper fix in Cuirass might be to ignore the primary key error (for
future reference, 1555 in the ‘sqlite-error’ exception above is
(logior 19 (ash 6 8)), which is SQLITE_CONSTRAINT_PRIMARYKEY in
<sqlite3.h>), as in the attached patch.  Thoughts?  I’ll push it if
there are no objections.
