kernel install: flash-kernel is sometimes never executed

[C de-Avillez]

When this happens, a kernel re-install works.
For example:

## SSH command: sudo apt-get -y dist-upgrade
+ ssh ubuntu@Armada1 -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o CheckHostIP=no -i /var/lib/ubuntu-iso-testing/kernel-sru/ssh-keys/qa-ubuntu 'sudo apt-get -y dist-upgrade'
Warning: Permanently added 'armada1' (ECDSA) to the list of known hosts.

There is a good chance this is related to both the kernel *and* kernel-flash being updated at the same time.

Replacing linux-armada by flash-kernel, after a chat with infinity in the #ubuntu-kernel channel.

Assigning to Adam, per his request

[Dave Jones (waveform)]

I believe the analysis that this was caused by both kernel *and* f-k being updated in the same apt run was spot on.

Furthermore, I *think* this was fixed in 3.98ubuntu10 which caused flash-kernel to (attempt to) run on every call to postinst maintscript, not just those involving a trigger (because pending triggers can be dropped on package upgrades. I'll set this to "Fix Released" as I'm fairly confident this is already fixed, but do feel free to set this back to "New" if it's still a issue.
