Evas filters: Fix order of header file includes

This fixes filters on Ubuntu 32 bits.

This was one hell of a weird bug to track down. Everything worked
like a charm on my 64 bit machines, but filters would simply fail
for no good reason: a safety check sees a NULL pointer when clearly
it was properly allocated.

Just after entering a function, the content of an RGBA_Image would
change, even though there was no memory write there. This made the
image data pointer NULL, and filters would fail miserably.

So I printed out the contents of the RGBA_Image, they changed. But
the memory itself had not changed. The size of the struct itself
had changed when jumping from one file to another! But its definition
had not! Non-sense!

Unless of course a system header file was included before config.h
and ino_t or off_t would switch between 32 and 64 bits...
