Alex Dadgar fd7d614ae4 Handle interfaces that only have link-local addrs 
This PR changes the fingerprint handling of network interfaces that only
contain link local addresses. The new behavior is to prefer globally
routable addresses and if none are detected, to fall back to link local
addresses if the operator hasn't disallowed it. This gives us pre 0.6
behavior for interfaces with only link local addresses but 0.6+ behavior
for IPv6 interfaces that will always have a link-local address.

Fixes https://github.com/hashicorp/nomad/issues/3005

Alex Dadgar 9497991590 Updated AWS speeds and network_speed now overrides 
This PR:

* Makes AWS network speeds more granular
* Makes `network_speed` an override and not a default
* Adds a default of 1000 MBits if no network link speed is detected.

Fixes #1985

Move network detection code to Linux-specific build 
Non-Linux build targets get the current default of 0.  This will allow
platform specific fingerprinting for network capabilities.
