[blob] Change null object memory mode to DUPLICATE
...
We never rely on that being equal to readonly. Just not being
writable. Maybe not even that given that the object is inert.
In prep for next commit, using default null pool.

There's nothing in hb_bytes_t that guarantees lexical ordering, and

Test case:
$ ./hb-shape GeezaPro.ttc -u U+0628,U+064A,U+064E,U+0651,U+0629

The mark positioning (kern table CrossStream kerning) only works if deleted
glyph (as result of ligation) is still in stream and pushed through the
state machine.
