From: venkata pyla <redacted>

The EFI and BOOT file system images are created non-reproducibly because
when `mkdosfs` create FAT file system it uses random values for volume-id
and creation time, this can be fixed by passing additional option
`--invariant` to `mkdosfs` that uses fixed volume-id and creation time.

Fixes: #73
