Make it possible to override the SDK path using an env var

The value will only be used if it matches an existing directory.
Useful for testing from Eclipse.

Note: this is a hack that does not change the preferences, so if the user
looks at Window > Preferences > Android, the path will be the preferences
one and not the overriden one.
