Add AC_LANG_DEFINES_PROVIDED to XORG_RAW_CPP to silence autoconf warnings
Since we're intentionally doing a special case to just check cpp output,
and not a full program compilation, add the magic macro to silence:
configure.ac:46: warning: AC_LANG_CONFTEST: no AC_LANG_SOURCE call detected in body
../../lib/autoconf/lang.m4:194: AC_LANG_CONFTEST is expanded from...
aclocal.m4:1077: XORG_PROG_RAWCPP is expanded from...
configure.ac:46: the top level
