Only use DATADIR in $fish_function_path if no-config is used

Browse Source 
This only uses the functions fish ships with, but still doesn't allow
any *customization*, which is the point of no-config.

This makes it a lot more usable, given that the actual normal prompt
and things are there.

This still doesn't set any colors, because we don't run
__fish_config_interactive because we don't read config.fish (any
config.fish), because that would run the snippets.
