verification/dot2k: Unify main.c templates

dot2k has 3 templates, one per monitor type, but the only difference
among them is the `DECLARE_DA_MON_*` call, keeping 3 almost identical
templates requires more work whenever we introduce a change.

This patch removes the 3 dot2k templates and replaces them with a
generic one, we then adjust the model type from the script.
