Revert "d/control: Add breaks on compressed 5.16 kernels"

See merge request !26

This would otherwise force 5.16 older than 5.16.0-1pureos2 off the
system as it can't be upraded due to it being removed from the archive
when 5.17 enters.

This reverts commit 57c06f68.

Switch to using uncompressed kernels by default and avoid vmlinuz/initrd.img copies

Closes linux-next#396 and #3

See merge request !25

This is to avoid that people do a partial upgrade of
linux-image-5.16.0-1-librem5 but not linux-image-librem5. While this
wouldn't break booting (as the old flash-kernel copes with uncompressed
kernels just fine) it also wouldn't free any space.

We need to drop this patch once 5.17.0-1 gets uploaded to prevent issues
when people have 5.16.0-1pureos1 (compressed kernel) installed and
update to 5.17 while 5.16.0-1pureos2 was already removed from the
archive as this would force 5.16.0-1pureos1 of the system *or* prevent
the upgrade.

Kernels 5.16.7pureos2 are uncompressed. Make sure the package that pulls
in new kernel versions gets updated with us so we're sure boot.scr finds
the uncompressed /boot/vmlinuz-5.16.0-1-librem5.

We should use the versioned ones. This requires the kernel to
be stored uncompressed.

Closes: #3

We want to avoid this since it makes roll backs to older kernel versions
harder and wastes space (not so much due to the kernel but more due to
the initramfs and the backup files).

This reverts commit 58b67e3f.

The current logic uses debconf as a registry which is a bug
since it always gives priority what's stored there making
it impossible to update unmodified conf files.

This makes the flash-kernel-installer udeb pretty useless
but we're not using d-i anyway.

`make bindeb-pkg` produces a compressed kernel so make sure
it gets uncompressed. This can also be dropped once we switch
to Debian's kernel.

Can be dropped once we use Debian's (uncompressed) kernel directly

Only until we switched to Debian's kernel.

This is similar to 451cf2ae.

Print the checked machine in the error messages. This helps when users
report errors or when flash-kernel runs in an image build machinery and
the machine type is passed in via FK_MACHINE.
