fstests: btrfs/029: add fixes for the kernel behavior change

Since fstests commit 866948e00073 ("btrfs/029: change the cross vfsmount
reflink test"), the test case will fail for older kernels (e.g. 5.14
kernels from SLE).

The failure is a false alert, but it would still take some time to
figure it out.
So add the fixes tag to make it more clear that it's a kernel behavior
change.
