Change and simplify `statvfs` conditions in FileSystemStats
`getfsstat` v.s. `getvfsstat` condition is different than `statfs` v.s. `statvfs`, so split each condition and simplify. For `get(v)fsstat` side, changed to check and use `getmntinfo`, because it is better than `get(v)fsstat` with fixed buffer size, and easier than improve it with dynamic buffer allocation. Signed-off-by: OBATA Akio <[email protected]> (cherry picked from commit d349995488a13687171a67efd981e986b3b703e5)
