Add in system init script for monitoring frequencies.

```
I created a system init script which will cause i7z to log out C states,
temperatures, and frequencies to files on the filesystem, making it easier to
parse these values and display the data. You can check out the script here:
https://github.com/rfkrocktk/i7zdaemon

If you'd like to include it in i7z, that'd be great. Apart from that, another
method (maybe DBus or something similar) would be great to be able to monitor
specific values for use in software like Conky.

Start by reviewing the linked i7zdaemon init script and the existing i7z monitoring entry points. The issue does not identify repository files or tests, and it leaves open whether the goal is to include the init script, expose monitoring values through another interface, or both; completion should be defined before implementation.
