[OE-core] [PATCH] ffmpeg: fix pkg-config utilization

[Nicolas Dechesne]

in config.log we can see:
WARNING: aarch64-linaro-linux-pkg-config not found, library detection may fail.

ffmpeg configure script is not looking for pkg-config at the rigt place since it
is assuming cross compilation. let's force its value in the recipe.

This patches 'fixes' library detection and brings the following diff:

* RDEPENDS: ++libxcb (>= 1.12) libxcb-shape (>= 1.12) libxcb-shm (>= 1.12) libxcb-xfixes (>= 1.12)
* PKGSIZE : 79167 -> 87823

Which basically means that the following conf options were left dangling in EXTRA_OECONF:

--enable-libxcb
--enable-libxcb-shm
--enable-libxcb-xfixes
--enable-libxcb-shape
