"sudo bootit" isn't working.

I installed it via cargo and can't use `bootit` with root privileges.

```
$ bootit scan
Error:   × This program must be run as root (try: sudo bootit ...)

$ sudo bootit scan
[sudo] password for sinokadev: 
sudo: bootit: command not found
$ sudo -E bootit scan
sudo: bootit: command not found
```
