The `jwebserver` tool is updated to allow the `-d` and `--directory` command line options, configuring the directory to serve, to accept a directory specified with a relative path. This is made available both when `jwebserver` is invoked as an executable:

```
jwebserver --directory some/relative/path
```

and as a module:

```
java --module jdk.httpserver --directory some/relative/path
```

As earlier, `-d` and `--directory` command line options also still support absolute paths.
