cryptsetup: add keyfile-offset= support
This is useful if your keyfile is a block device, and you want to use a specific part of it, such as an area between the MBR and the first partition. This feature is documented in the Arch wiki[0], and has been supported by the Arch initscripts, so would be nice to get this into systemd. This requires libcryptsetup >= 1.4.2 (released 12.4.2012). Acked-by: Paul Menzel <paulepanter@users.sourceforge.net> [0]: <https://wiki.archlinux.org/index.php/System_Encryption_with_LUKS# Storing_the_key_between_MBR_and_1st_partition>
