Public bug reported:
[Impact]
* When resigning grub in a PPA, one can satisfy the build-depends from the
main Ubuntu Archive, without PPA signature ready yet.
* In such cases, grub2-signed is missbuilt with signature from an old PPA
build attached to a newer binary, resulting in validation errors.
* Add a check to ensure that signed grub & build-depends grub are the same
[Test Case]
* Copy grub2 from -updates into PPA and await signing
* Copy grub2-signed from Ubuntu Archive -proposed into PPA
* Observe that grub2-signed FTBFS, instead of successfully producing
uninstallable/unverifiable debs
* Copy grub2 from -proposed into PPA, and await signing
* Retry grub2-signed build, which should now succeed
[Regression Potential]
* Only a build-time quickcheck is added, without any other changes of
how signed grub efi images are assembled.
[Other Info]
* Previously this issue resulted in miss built UC20 grub copies
