feat(t430): boot installed linux from genode vm

[dckc]

refs: #49

I got a basic VM to boot (#178). Now I'm trying to reproduce the Apr 2021 results from Starting an existing Linux installation from Sculpt, but when I start the vm launcher referring to my local vbox6 package, I get Error: spurious exception during deploy update over and over:

[runtime -> wifi_drv] create uplink for net device wlan0
[runtime -> nic_router] [uplink] NIC sessions: 1
[runtime -> nic_router] [uplink] dynamic IP config: interface 192.168.86.99/24, gateway 192.168.86.1, P2P 0, DNS server 192.
168.86.1

This PR attempts to detail all the steps I took, which are intended to match the Apr 2021 item (as well as March 2019 Tweaking existent packages to your needs):

• chore(t430): provided vbox6 pkg, raw
• chore(t430): parameterize extra-repo $(GENODE)
• feat(t430): legacy-grub, check-ahci, linux.vmdk
• chore(t430): prepare to make local vbox6 pkg
• chore(t430): move local vbox6 config from runtime to init.config
• chore(t430): point vbox6 package archives to local raw
• feat(t430): vm launcher using block device
• chore(t430): generated vmdk file
• chore(t430): point machine.vbox6 at linux.vmdk
• feat(t430): boot linux from vbox6 in genode
• fixup: deploy local packages
• fixup: linux-pt.vmdk too
