Module fstab should not add keyfile/password options in crypttab when luksbootkeyfile module is disabled

[eugenesan]

I am working on Kubuntu installer with systemd-boot, encrypted root, no boot partition.
So far I managed to get it working by altering only config files but there is one issue that requires code change.

When I remove luksbootkeyfile, fstab still adds keyfile/password option to crypttab, making target unbootable without manual edit of crypttab.

I guess the following logic

calamares/src/modules/fstab/main.py

Line 159 in 1645874

if any([p["mountPoint"] == "/"

should check when luksbootkeyfile is disabled or/and when bootloader doesn't require access to /boot as it is with systemd-boot which boots linux/initrd from EFI.

Tested on Ubuntu 24.04, Calamares 3.3.5

I think we should fix line:

calamares/src/modules/fstab/main.py

Line 154 in 1645874

password = "/crypto_keyfile.bin"

It should be "none" by default and only get set to the keyfile path if the keyfile exists.
