Add IPC port to manifest

If the port for an application is not available, ql-tipc
immediately returns with an error without waiting for the port
unless that port is listed in the manifest. This adds the AVB
port to the manifest to fix a race between the bootloader
connecting to AVB and the app starting during boot.
