Title: Enable to set clone locations with env

This patch enables users to specify the destination directory of cloning gems with two environment vars:

- GEMSRC_CLONE_ROOT: the root directory to clone
- GEMSRC_CLONE_DIR: the directory name of root of repository

Examples:

```sh
GEMSRC_CLONE_ROOT=$HOME/repos gem install gem-src
GEMSRC_CLONE_DIR=src gem install gem-src
```
