Refactor statfs/statvfs type check
Turn it into a configure-type typedef, which allows us to reduce the amount of duplicated code and clean up some #ifdef magic in the code itself. Adjust some of the other defined checks to look at the headers available rather than trying to pull in the right ones based on configure checks.
