Integrate APT, PIP results

Each of those tools can output their own result. It's better to integrate them in our final result also.

1. APT
```
$ apt list --installed
```

List up only outdated packages:
```bash
$ apt list --installed | sed -nr 's_(.*)/(.*) (.*) (.*) (.*)upgradable to: (.*)]_\1,\3,\4,\6_p'
```
Implemented in: [apt_check.sh](../blob/master/apt_check.sh)

2. PIP
```bash
$ pip list -o
```
