NetBSD doesn't provide struct statfs, make use of struct statvfs

[joerg]

One good question is whether using statvfs(3) shouldn't be the default as it is the POSIX interface.

Unfortunately, that will not work as linux does not define the MNT_LOCAL flag and struct statvfs does not contain the f_type magic field.
