update "The DragonFly Booting Process"

[Victor Balada Diaz]

Hi,
the detailed log:

	- Delete the references to device.hints because we don't use it.

	- Change various references from FreeBSD to &os;.

	- Fix the example in the OS selector boot menu.

	- Use options of the DragonFly boot menu when makes sense.

	- Delete a reference to kernel.GENERIC because we don't have
	  it on the ISO.
