virtme-prep-kdir-mods: delete existing $MODDIR/modules.dep at beginning

If preparation process of .virtme_mods is interrupted, the directory will be in an inconsistent state and needs to updated on the next run. Now we use $MODDIR/modules.dep file in run.py to check if virtme_mods needs to be updated, so we can delete the modules.dep file at the beginning to ensure that if the command is interrupted, we will update the directory on the next run.
