test-tool: handle the `-C <directory>` option just like `git`

In preparation for moving `git serve` into `test-tool` (because it
really is only used by the test suite), we teach the `test-tool` the
useful trick to change the working directory before running the test
command, which will avoid introducing subshells in the test code.
