Change hash files only if gpg card is present

Update_checksum was already changing files in /boot, befor checking for
gpg card. If no card is present, the user will end up in the recovery
next time instead of getting the same dialog again. Therefore, the
confirm_gpg_card should be checked before altering files.

The dead -u flag/$update_counter is used to mark the necessisty to
update the hash files now.
