Yes, that's probably a better idea. We don't even need anything in the test suites if we set `treesit-extra-load-path` in the Makefile, as in this patch.

(We could set an environment variable instead, but then it would need decoding in each tree-sitter test as well, and the change to the Makefile wouldn't really be simpler.)
