Rework extract_single_file() temp file creation

We were a bit juryrigged using one call to mkstemp() before rather than
extracting the new files side-by-side and doing our comparisons there. We
were also facing some permissions issues. Instead, make our life easier by
extracting all temp files to a '.paccheck' extension, doing our md5
comparisons, and then taking the correct actions.

Still to be done here- a cleanup of the use of PATH_MAX which should not be
necessary if we use dynamic allocation on the heap.
