Fix loading of the example baremetal kernel with the fixed ELF kernel
loader:
- Remove the "RAM" address space so virtual and physical address match.
- Remove the 0x200-byte padding now that entry point address is used.

TEST=Run baremetal as in tools/examples/baremetal/README.md

rwroot automatically adds root=/dev/vd[a-z], but the example image
actually uses /dev/vda5. This leads to confusion when two root= kernel
command line arguments are passed in and only one of them works.
Therefore we use rwdisk instead which doesn't add the kernel argument.

Two examples are added. A simple one and one with network
configured.
The examples are written in a way they can be integrated
with the mdbook to form a tutorial. This will ensure the
tutorial code snippets stay up to date.
The documentation for networking is added after
https://crrev.com/c/3237468 is merged.
