migration: add remaining params->has_* = true in migration_instance_init()

Some of params->has_* = true are missing in migration_instance_init, this
causes migrate_params_check() to skip some tests, allowing some
unsupported scenarios.

Fix this by adding all missing params->has_* = true in
migration_instance_init().

Fixes: 69ef1f36 ("migration: define 'tls-creds' and 'tls-hostname' migration parameters")
Fixes: 1d58872a ("migration: do not wait for free thread")
Fixes: d2f1d29b ("migration: add support for a "tls-authz" migration parameter")
