Make compilation fail if CONFIG_COMPAT=y

v4l2-compat-ioctl32 contains a security vulnerability mentioned
in the Google Android Security Bulletin for December 2017
(CVE-2017-13166, A-34624167).

We do not use this file, our kernel config has CONFIG_COMPAT=n.
And the patch is quite substantial.
This patch makes the compilation fail if the config option is
enabled.
