x86: Add ramboot and nfsboot commands in x86-common.h
It is very common in the debug stage to test U-Boot loading a linux kernel. The commands to boot linux kernel with ramdisk and nfs as the root are common to all x86 targets, so it makes sense to add them as the U-Boot default environment in x86-common.h.
