General cross platform/compatibility support

[Ongy]

The current version of monky only supports linux.
Some modules can be ported rather quickly, (CPU, Battery, Memory etc.).
Others may only be possible in parts (Network (netlink with dynamic), IP (netlink for events)).

The main target for compatibility would be some BSD.

I'm also not quite sure how much of current monky works on arm (or general not x86) hardware.
CPU thermal-zone guessing is most likely x86 only, all others should work (maybe ffi problems).

Kernel support has low priority, until users request it.
Hardware support is limited by (my/contributor) hardware.

I can assist in testing on armv7

Is that 32bit? If so it would be nice to test the disk module on it (It should work now).

Also on arm, the cpu temperature may fail. It checks if the thermal zone is of a specific type. But I don't know if arm uses the same type. https://github.com/monky-hs/monky/blob/master/Monky/CPU.hs#L124
