Rename and update script to add misc/akaros directory to path

This is where the go_akaros_amd64_exec script is that is used by 'go
run' to decide how to actually execute a go binary that is built.  In
the case of akaros, this is done through qemu on localhost (for now).
Actual implementation of the go_akaros_amd64_exec script

It assumes you have an instance of akaros running in qemu on localhost
which can take commands passed through it via netcat and execute them.
The 'goclient.sh' script in kfs/bin on akaros does the required client
side setup to handle commands sent from this script.  After laucnhing
akaros just fire up busybox and run goclient.sh and wait for it to say
'listen started'. After that you can simply run 'go run XXX' on your
linux box and have the commands piped through to akaros and the results
sent back.
