aktualizr: Fix virtual secondary support.

Use /etc/sota/ecus as using /var/sota/ecus was conflicting with the
provisioning recipes that also use /var/sota. Not totally ideal, but the
best compromise I could find.

 * `SOTA_DEPLOY_CREDENTIALS` - when set to '1' (default value), deploys credentials to the built image. Override it in `local.conf` to built a generic image that can be provisioned manually after the build.
 * `SOTA_CLIENT_PROV` - which provisioning method to use. Valid options are https://github.com/advancedtelematic/aktualizr/blob/master/docs/automatic-provisioning.adoc[`aktualizr-auto-prov`], https://github.com/advancedtelematic/aktualizr/blob/master/docs/implicit-provisioning.adoc[`aktualizr-ca-implicit-prov`], and https://github.com/advancedtelematic/aktualizr/blob/master/docs/hsm-provisioning.adoc[`aktualizr-hsm-prov`]. The default is `aktualizr-auto-prov`. This can also be set to an empty string to avoid using a provisioning recipe.
 * `SOTA_CLIENT_FEATURES` - extensions to aktualizr. The only valid options are `hsm` (to build with HSM support) and `secondary-network` (to set up a simulated 'in-vehicle' network with support for a primary node with a DHCP server and a secondary node with a DHCP client).
-* `SOTA_SECONDARY_ECUS` - a list of paths separated by spaces of JSON configuration files for virtual secondaries on the host. These will be installed into `/var/sota/ecus` on the device.
-* `SOTA_VIRTUAL_SECONDARIES` - a list of paths separated by spaces of JSON configuration files for virtual secondaries installed on the device. If `SOTA_SECONDARY_ECUS` is used to install them, then you can expect them to be installed in `/var/sota/ecus`.
+* `SOTA_SECONDARY_CONFIG_DIR` - a directory containing JSON configuration files for virtual secondaries on the host. These will be installed into `/etc/sota/ecus` on the device and automatically provided to aktualizr.
