Bug Description
On Ubuntu 22.04.2 with the default mtools version 4.0.33-
The mformat tool from the above package fails in a way that wasn't failing before.
```
Warning: no active (bootable) partition present
Weird: read size (142561) not a multiple of sector size (512)
buffer_flush: short write
Error writing boot sector
```
This is working fine with my previous old version mtools 4.0.18 and also with the real 4.0.33 version (not the "really" version).
I can't point you to the exact commit that fixes this bug because GNU mtools doesn't seem to have a public git tree.
Can we please ship version 4.0.33 rather than 4.0.32 with Ubuntu 22.04?

I think it's related to image size. Here's an image that mtools 4.0.32 fails on:
$ fdisk -l foo.img
Disk foo.img: 69.89 MiB, 73285632 bytes, 143136 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000
Device Boot Start End Sectors Size Id Type
foo.img1 * 63 143135 143073 69.9M 6 FAT16
$ hexdump -C foo.img
