env/freebsd-amd64: add ability to create images from non-release versions

Add FreeBSD 12.0 as -ALPHA8 snapshot.
Make the binary freebsd-update step optional (it's available only for releases).

Use the downloaded vanilla image as a base image of the now qcow2 formated disk.qcow2.
This saves the initial cp vanilla to disk.raw step, which is kind of slow.
disk.qcow2 is converted back to raw before the GCE image is archived.
This might also achieve better sparse images, haven't compared though.
