Remove nix-daemon.socket dependency of /nix/store

Browse Source 
The dependency causes a cycle as the nix store will be mounted after the
network is ready, which itself depends on the socket.target which
requires the nix-daemon.socket to be ready too.

# The nix-daemon.socket has an unnecessary dependency over the /nix/store
# mount point. But that mount point won't be provided until the network is
# ready. However, the network-address-eno1.service, has a dependency over
# sockets.target, causing a cycle.
# One solution is to make the nix-daemon.socket depend only on the socket
# patch (which is already covered by ConditionPathIsReadWrite =
# /nix/var/nix/daemon-socket), instead on the /nix/store.
