Since the custom password is used to set the GPG admin
password as well as the TPM and GPG user passwords, an
8-character minimum is required. Inform the user of this,
and validate custom password length upon entry.

If /boot isn't mounted, we can't read the HOTP counter, so no
point in reading from the TPM. This speeds up getting to the
main menu in the case of an inaccessible or non-existant /boot.

If kexec-sign-config fails due to GPG key not present,
the double die() results in a kernel panic (and if it didn't,
/boot would be left mounted RW). Fix this by removing call to
die() and ensuring /boot remounted RO regardless checksum
update success or failure.

Normally we resort to default passwords for OEM reset, however we have a
use case where it would be convenient to set a custom password instead.
This patch adds a simple prompt (that defaults to the defaults if you
hit Enter) that enables someone using the OEM reset to enter a single
password that will replace the defaults (TPM, GPG Admin, GPG User).
If the user chooses to flash a "cleaned" ROM (not persisting settings
or GPG keys) then the signatures on /boot are no longer valid, so clear
them out. This allows for the OEM factory reset prompt to be shown on
the next boot.

Users may wish to temporarily boot an OS from a drive other than
their primary boot drive, without changing the default and saving
to ROM. Mounting /boot after changing the device selection
facilitates this by allowing the user to then choose an unsafe boot
from the newly-selected boot drive.

Initial card detection can sometimes fail, so prompt the user
to remove/reinsert their GPG card before retrying. Since
errexit is likely set, disable it prior to calling --card-status so
we can handle the error ourself, then re-set if necessary when done.
