dont ignore the CFLAGS from pkg-config check for libseccomp.

If the header files for libseccomp are not in the default include dir the following check for fchmodat2 fails. This patch would fix the issue.

CFLAGS="$LIBSECCOMP_CFLAGS $CXXFLAGS"

This use of $CXXFLAGS doesn't look right. Is it intentional?
Would you like to open a pull request for this?

well I am honest i was just lazy and i copied the CXXFLAGS part for testing. but you are right i should probably use CFLAGS in the CFLAGS part.
