In preparation for enabling Dracut-based ramdisks, this change
factors out functionality that is common to both busybox and Dracut
ramdisks. Said functionality is moved to a ramdisk-base element
which is added as a dependency of the ramdisk element. ramdisk now
only contains the functionality specific to building busybox-based
ramdisks.

This change adds support for retrieving the IP
through DHCP if 'ip' was not provided as a kernel
command-line argument by pxelinux. This is used
when the kernel/ramdisk is booted by virtual media.
