tests/kms_cursor_crc: Fix the cursor tests to work on CHV

cursor updates on pipe C at negative X coordinates when the cursor is
visible.
This was done in the following kernel commit:

kms_chv_cursor_fail was created to test this issue, but it also happens
in kms_cursor_crc, so workaround it there too.
