Update shirou/gopsutil dep to use non-GPL code

Browse source 
Previously used `github.com/shirou/gopsutil`[1], used some GPL code [2].
This was somewhat unintentional, and was addressed later [3].

Due to being late in the cycle of Nomad release when this is noticed,
and time elapsed since we updated the dependency, we want to be
conservative in our package updates.

As such, we opted to go with forking the repo to use the previously used
version with the GPL removal code commit, done in [4].
