compilation fails for gcc-4.4.6 about ndpi-netfilter

[tsarangi]

I am using gcc-4.4.6 where BYTE_ORDER is not predefined. In ndpi_define.h, if __KERNEL__ is not defined, then there is no way to find out BYTE_ORDER for the machine. It doesn't include endian.h from /usr/include.

Here is a patch that works, but spews a bunch of __redefine warnings from the compiler.
