media-ctl: fix build with old kernel headers

Add a patch to fix the recurrent media-ctl build problems with
toolchains based on relatively old (< 2.6.39) kernel headers.

Finally fixes:

+Subject: [PATCH] Add kernel headers for compatibility with old toolchains
+
+The media controller mechanism is relatively new in the Linux kernel,
+and therefore all toolchains don't yet have the necessary
+headers. This patch makes sure that media-ctl provides such headers,
+as was already the case with v4l2-common.h, v4l2-subdev.h and
+videodev2.h.
