Spurious error message on Tails sticks installed a long time ago

A while ago, the size of the system partition created by Tails Installer was 2500 MiB = 2500*1024*1024 = 2621440000 bytes.

Since Tails 6.6 we treat those as an error:

01:00:36.349 '[' 2621440000 -lt 4292870144 ]
01:00:36.350 echo 'The system partition was not correctly resized ' '(expected at least 4292870144, got 2621440000).'
The system partition was not correctly resized  (expected at least 4292870144, got 2621440000).

01:00:36.357 The partition table is invalid
01:00:36.359 touch /run/repartitioning-failed

… and we report it to the user. A few already sent us bug reports since we released that.

I think we should do something like this instead:

@boyska & @segfault, any reason not to?
