[IMP] runbot: automatically link logs to build

The linked build is extracted from dbname via a trigger on new row
creation.

This improve rendering of build page.

A migration script is added to link existing logging entries to
corresponding build and remove invalid ones.
Note that this migration script can take a long time.
