[OE-core] [PATCH] ffmpeg: fix build when DISTRO_FEATURES doesn't contain x11

[Jonathan Liu]

If avdevice is enabled, libxv is used if it is detected by configure
for the XV outdev. However, we can't depend on libxv for avdevice when
DISTRO_FEATURES doesn't contain x11 as this will result in an error.

Fix this by adding a libxv dependency only when the avdevice
PACKAGECONFIG is enabled and DISTRO_FEATURES contains x11. XV outdev
is only one of many that are supported by avdevice so it is still
useful to enable avdevice even if libxv is not available.
