libblkid: vfat: Fix reading FAT16 boot label and serial id

Older FAT16 variants do not have to contain boot label or serial id. Boot
sign 0x28 indicates that only serial id is present and boot sign 0x29
indicates that both boot label and serial id is present. Other boot sign
values (e.g. zero) indicates older FAT16 variant without boot label and
boot sign.
