mpd: fix incorrect use of mkIf (#8504)

Currently, if cfg.network.listenAddress is set to "any", MPD_HOST causes
partial evaluation which fails the sanity check while trying to build a
home-manager generation. Hence make a separate attrset for MPD_HOST
which will be evaluated conditionally and then concatenated.
