Find fishd file even when $HOME is unset

Browse source 
env.cpp sets up $HOME based on the current user, if it's not inherited
from the environment. fishd_get_config should be using the same
calculated value of $HOME. To that end, move universal variable
initialization to after $HOME is set up, and read the value from the
fish environment instead of using getenv().

Fixes #1725.
