jbhook1: More effectively setup avs boot config

Browse Source 
The NVRAM redirection was silently failing because the prop
delete/recreate pair didn't work. This just recreates the entire
config from scratch instead, which guarantees success every time.
By making the NVRAM type "fs", we also make it easier to debug
any issues that people may have.
