encoding/jsonschema: do not let cue/load walk up to the git root
When using `GODEBUG=gocachehash=1 go test .`, the number of testInput
lines goes down dramatically after the change, as the test cache logic
no longer needs to stat hundreds of files in parent directories.
$ grep testInput before.txt | wc -l
3960
$ grep testInput after.txt | wc -l
1291
