[Bug 1617600] [NEW] No encryption password prompt with plymouth

[Rob Tongue]

Public bug reported:

After installing fresh, system booted fine and prompted for password to
decrypt root partition.   After running the latest updates, now the
screen stays black on boot, but blindly entering password works to get
the system booted.   This could get very confusing for users, as you now
have the option when installing to encrypt the entire filesystem.   I
reinstalled thinking my system broke, when it didn't really, I just
can't see the password box.
