[PATCH igt v7 3/4] tests/core_prop_blob: Add multiple blobs per connection

[Daniel Stone <daniels@collabora.com>]

This should hit the bug fixed in:
XXX FIXME INSERT SEANPAUL COMMIT CITE

which was introduced with the initial blob support in:
    commit e2f5d2ea479b9b2619965d43db70939589afe43a
    Author: Daniel Stone <daniels@collabora.com>

        drm/mode: Add user blob-creation ioctl

        Add an ioctl which allows users to create blob properties from supplied
        data. Currently this only supports modes, creating a drm_display_mode from
        the userspace drm_mode_modeinfo.

        v2: Removed size/type checks.
            Rebased on new patches to allow error propagation from create_blob,
            as well as avoiding double-allocation.
