boot: move cluster list to 1FE0h:2200h (128 KiB file, up to /L 0x200)
...
1FE0h:2200h happens to be linear 22000h. Like the memory map
update to the FAT32 loaders for #127 this allows to load a
file of up to 128 KiB (rounded to cluster size) with an /L
parameter for SYS of up to 0x200.

boot32: fix very old bug, init high byte of fat_secshift
...
It turned out that this loader was severely broken for many years,
at least since 2012 (the git repo's creation). This variable was
read as a word to set cx for a loop, but only the low byte had
been written. The high byte happened to be 0EEh so cn_loop would
always zero out the FAT sector to read.
This _happened_ to work if the first root directory cluster and
all the kernel file clusters were all referenced in the first
sector of the FAT. Otherwise it would blow up.
