gogio: [Android] add support for querying apps

Previously, it was impossible to identify if a specific app
was installed on the user device. It was also impossible to
launch a external app from Gio using Intent.

Now, you can use `-queries` with a comma separed package names,
like `com.another.app`. That allows you to launch Intent to
`com.another.app`.
