tests: fix test-chg to ignore a warning about being unable to set locale
This is apparently coming from bash when bash is providing the sh that we're
using to execute the .sh file generated by run-tests for this test.
Bash on my machine:
```
$ sh --version

$ sh
sh-5.1$ LC_CTYPE=unsupported_value echo hi
sh: warning: setlocale: LC_CTYPE: cannot change locale (unsupported_value): No such file or directory
hi
