Dear seabios maintainers,

this package currently uses debhelper with an ad-hoc sequence of steps
in d/rules. This long list of steps can be shortened and greatly
simplified by using the standard dh sequence.

You can find a MR that changes `d/rules` to use the standard dh sequence at:

https://salsa.debian.org/qemu-team/seabios/-/merge_requests/4

According to diffoscope, the generated binary package is identical to
the current one.
