description:
cargo.mk: move CARGO_FEATURES from lang/ncspot to here

It seems to be a generally useful feature. If a package supports
optional cargo dependencies then you may now (instead of messing with
CARGO_ARGS directly) set in your Makefile for example:

CARGO_NO_DEFAULT_FEATURES=      YES
CARGO_FEATURES+=                dbus pulseaudio
