`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.

NetBSD APM is supported other than i386 too, emulate API,
so change to detect with MI support header.
Additionally, catch up support codes to others.
