This makes the output consistent on big-endian systems.

The RGB32 pixel format is RGBA/BGRA depending on target
endianness - make sure to convert it to one specific format for
the framecrc tests.

This fixes the pngparser fate test on big endian.

being set.

This makes only tests actually using avconv depend on it.
The remaining tests already depend on what they need.
