Support modular dm-crypt

Previously dm-crypt had to be statically compiled into the kernel, which
is cumbersome, not well documented, and makes the kernel larger.

This supports dm-crypt being an external module, adding rmmod and
modprobe to the initramfs, and copying in the relevant kernel modules
directory, stripping out graphics device support, bluetooth, sound,
virtualization, and networking support modules.

This also updates the copyright year.
