>Description:
One of the error checks wasn't properly integrated into r206043 as part of bin/145101 (it was in the 2nd patch, not the first one).

This patch also reorders the headers so that it makes the actual dependencies for libpkg more apparent and fixes indentation according to jkh's `coding style' in one spot.
>How-To-Repeat:
These are error conditions that won't occur 99.9% of the time (unless uname(2) fails), but will occur given proper circumstances.
>Fix:
See attached patch.
