Attachment: Bug 1392447 - Fix up Servo_StyleSheet_GetOrigin for Linux 32-bit ABI.

Bindgen bitfield enums don't work as return values with the Linux 32-bit ABI at
the moment because they wrap the value in a struct.

This causes the Rust side to believe the caller will pass along space for the
struct return value, while C++ believes it's just an integer value.
