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).
