[PATCH 03/13] selftests: ublk: add io_uring uapi header

[Ming Lei <ming.lei@xxxxxxxxxx>]

Add io_uring UAPI header so that ublk can work with latest uapi
definition.

Fix the following build failure:

stripe.c: In function ‘stripe_to_uring_op’:
stripe.c:120:29: error: ‘IORING_OP_READV_FIXED’ undeclared (first use in this function); did you mean ‘IORING_OP_READ_FIXED’?
  120 |                 return zc ? IORING_OP_READV_FIXED : IORING_OP_READV;
      |                             ^~~~~~~~~~~~~~~~~~~~~
      |                             IORING_OP_READ_FIXED
