[PATCH] 9pfs: fix missing sys/mount.h include

[Christian Schoenebeck]

Fixes the following build error:

  fsdev/file-op-9p.h:156:56: error: declaration of 'struct statfs' will
  not be visible outside of this function [-Werror,-Wvisibility]
    int (*statfs)(FsContext *s, V9fsPath *path, struct statfs *stbuf);
                                                       ^

As Windows neither has statfs, nor sys/mount.h, don't include it there.
