include config-compat.h with gcc -include command

From: Trent Piepho <xyzzy@speakeasy.org>

The kernel's config settings from autoconf.h are overridden by the file
config-compat.h, which is included from compat.h.  Code compiled before
compat.h is included will see the kernel's settings, while code compiled
after will see v4l-dvb's version of the settings.  This has caused hard
to track down bugs on more than one occasion.

Always including compat.h first will not work, as some of the
compatibility code requires that certain kernel headers be included first
in order to work correctly.

This patch makes config-compat.h be included second (after the kernel's
autoconf.h) for every file by using a gcc "-include" command line option,
the same way the kernel autoconf.h file is included.  This should
eliminate the problem of config-compat.h not being included in the right
spot.
