bitbake: toaster: fix migration code for MySQL

This is a patch that fixes the 0004, 0005 migrations of the toaster
model to get them to properly work with MySQL.

These migrations had a conflict around Build.timespent field.
The sqlite3 constraits were not enough to detect the conflict, and
the migrations worked as expected.

MySQL objected to adding the field twice, so I did regenerate
the migrations with the correct model listing. The net effect
is the same, so the migrations work the same, but now we
can use these two migration on the MySQL and other more advanced
SQL engines.
