FreeBSD port

[Danik2343]

Current state: FreeBSD port not available and not building in FreeBSD

Wanted state: FreeBSD port available or Fastfetch build for FreeBSD

Why the change is sensible: Adding support to other OSes

Will look into this, as soon as i finished exams for this semester. Currently the newly added MacOS support is taking all of the time i have left from learning.

BSD is now relatively good supported in my VM, can you please test it and give feedback?

[LinusDierheimer]

BSD is now fully supported.
