bitbake: toaster: set non-hideable columns for build tasks table

The task, recipe and order columns in the build tasks table
should not be hideable. If they are, it's possible for the
table to have all of its columns hidden so that it no longer
displays.

Set the hideable property to prevent these columns from being
hidden.
