Updated patch-bktr to make ffmpeg compile on DragonFly

["Steve O'Hara-Smith" <steve@xxxxxxxxxx>]

	Hi,

	The attached file is a replacement for
multimedia/ffmpeg/patches/patch-bktr that fixes a typo in the condition for
building on DragonFly in libavdevice/bktr.c.

	I have raised the issue upstream as well so hopefully it will get
fixed upstream soon, in the meantime this gets ffmpeg building.
