d/rules: test for version mismatch

[panlinux]

Fixes: #3154

Why is this needed?

This prevents package builders and uploaders from forgetting to also update the VERSION in uaclient/version.py if a new upstream version is created. Since this is a native package in ubuntu, every single upload will be a new upstream version as well.

Test Steps

Change version in d/changelog to something different from uaclient/version.py's VERSION, and build the package. The build should fail.

The script tools/check-versions-are-consistend.py doesn't work for GH builds, because they add an ubuntu1 suffix:

$ python3 tools/check-versions-are-consistent.py 
version.py says "32.3" but changelog says "32.3ubuntu1~1.gbp761c11~noble1"

Maybe we could remove that ubuntu1 suffix, I don't know where it's added, but doesn't seem necessary and might be old cruft.

I'm completely up for removing the suffix - just need to check the impact this would have to our daily builds on LP though

[panlinux]

Where is that suffix added?
