User API header file required to generate bindings in v4l2-sys is not part of libv4l2.

Instead, directly check if UAPI header file is present on FreeBSD and extend compiler's include paths.
Or guide user towards necessary package if header file is missing.

Don't forget to add a comment to the code explaining that we don't need the libv4l2 headers either to build v4l2-sys, just the Linux UAPI header.

I'm not certain whether that's provided by libv4l2 or another package on FreeBSD. Is it https://www.freshports.org/multimedia/v4l_compat?
