website: Provide multiple init alternatives in ubuntu image

Unfortunately it is not possible to specify a single m5 powered init
script working under every circumstance. For example when using a KVM
CPU, the default coprocessor implementation of m5 ops won't be
recognised by the host; same applies for the semihosting one; the memory
mapped version on the other hand is not compatible with a Fast Model CPU
which instead requires the semihosting interface.

To overcome these limitations, we provide a single disk image with
multiple init scripts. The user would have to point to the correct init
script depending on the simulation environment.

/init.gem5 -> If using a "standard" cpu
/init.addr.gem5 -> If using a kvm cpu
/init.semi.gem5 -> If using a fast models cpu
