[Cuis] OSProcess status

I updated the Cuis-Smalltalk-OSProcess package on github, and I think
it should work better on Mac now. I fixed OSProcess class>>platformName
and also reverted my last change to OSProcess class>>isUnix, which is
not required when platformName works correctly.
As before, many of the OSProcess tests require an interpreter VM (not
Cog) to run, but aside from that I think that most important functions
should work in OSProcess on Mac. Please let me know if that is not the
case.
This change might cause a problem for some versions of Pharo that have
a broken platformName implementation, but I think I will let that be a
problem for someone else to worry about.
