[PATCH 1/2] tools: fix userspace compilation with new test_xarray changes

[Luis Chamberlain]

Liam reported that compiling the test_xarray on userspace was broken.
I was not even aware that was possible but you can via and you can
run these tests in userspace with:

make -C tools/testing/radix-tree
/tools/testing/radix-tree/xarray

Add the two helpers we need to fix compilation. We don't need a
userspace schedule() so just make it do nothing.
