LibUnicode: Stop generating Block property data

We started generating this data in commit 0505e03, but it was unused.
It's still not used, so let's remove it, rather than bloating the size
of libunicode.so with unused data. If we need it in the future, it's
trivial to add back.

Note we *have* always used the block name data from that commit, and
that is still present here.
