Exercises the new blob-creation ioctl, testing lifetimes and behaviour
of user-created blobs, as well as exercising all the invariant
conditions we guarantee from modes exposed as blob properties.
v2: Renamed to core_prop_blob, skip test if blob not available.
v3: No changes.
v4: Consistently return 0/errno.
v5: Use do_ioctl_err and igt_assert_fd.
Use igt_assert_*() helper macros rather than direct igt_assert().
