Jeff King 04724222d5 test-dump-cache-tree: avoid overflow of cache-tree name ...

When dumping a cache-tree, we sprintf sub-tree names directly
into a fixed-size buffer, which can overflow. We can
trivially fix this by converting to xsnprintf to at least
notice and die.

This probably should handle arbitrary-sized names, but
there's not much point. It's used only by the test scripts,
so the trivial fix is enough.
