These tests are meant to run without user interaction, so reading from
stdin isn't something we want to be doing.

What you should do is add more subtests for the different cursors sizes.
And you should make the 128x128 and 256x256 subtests skip if the kernel
refuses the specific cursor size. By using igt_subtest_f() you can avoid
a bunch of duplicated code for iterating the subtests.
