gstreamer-video: new test failure on big-endian architectures with v0.21.1

I get a strange test failure building gstreamer-rs v0.21.1 for Fedora - tests pass on all architectures, except for s390x (our only supported big-endian architecture). From the build log:

The lists are identical except two adjacent elements that are swapped: P01010le, Nv1210le32 vs. Nv1210le32, P01010le

It appears that this code has recently changed? 635b3161
