osbase/fat32: adopt structfs

Change the external interface of the FAT32 writer to take a
structfs.Tree instead of a FAT32-specific data structure. Producers of
file system data are no longer specific to FAT32.

With these changes, the blkio package becomes obsolete. The
LazyFileReader did not actually work as intended when used with
osbase/fat32, because fat32 copies data with io.CopyN and thus stops
reading before reaching EOF, so the LazyFileReader is never closed. The
new Blob interface requires the consumer to explicitly Open and Close.
