Fix CMAKE_HOST_SYSTEM_NAME on SunOS
In commit 0bbd993f (Make CMAKE_HOST_SYSTEM_NAME available in scripting
context, 2016-12-26) we added a call to `uname` that checks for a zero
return value. However, on Solaris the `uname(2)` manual [1] says that
on success a non-negative value is returned. Fix our return code check
so that we detect the `SunOS` name correctly.
