Optional dmenu support in sndev (#2603)

If dmenu is installed, `sndev start` will now prompt the user to select which profiles should be used with docker-compose.

However, this means COMPOSE_PROFILES in .env.local is now ignored during `sndev start` if dmenu is installed, but not during `sndev delete`.

This means that `sndev delete` would not delete containers previously started by `sndev start` anymore.

To fix this, and since I think this is what it should have done anyway, `sndev delete` now also ignores COMPOSE_PROFILES from .env.local and always deletes all containers instead.
