[ptxdist] [PATCH 2/5] RAUC: add option to enable streaming support

[Enrico Jorns <ejo@pengutronix.de>]

Enable it by default so that default installation can benefit from this.
Can be deactivated for saving space or for deactivating network
functionality.
Web server must support HTTP range requests for this and NBD support
must be enabled in kernel.
