Deal with memory requirements check in tails-upgrade-frontend-wrapper vs Jessie
In 01c88c1 it was lowered since (at least on the automated test
suite’s “hardware”) Jessie doesn’t leave enough free non-buffer/cache
memory for tails-upgrade-frontend-wrapper to do the actual upgrade
check.
We probably want to do something smarter, or verify that this new number is safe.
