remux prerm script fails on reenable

[Jayy001]

Just did a fresh update from 2.14.1.866 to 2.14.3.1005 (Have not installed ddvk-hacks, can confirm everything is working fine)

After running toltecctl reenable, it does throw an error which it shouldn't do over a unit file not existing.

Full log:

We should replace the call to systemctl disable --now remux in preremove with something similar to what is done for tarnish.

toltec/package/oxide/package

Lines 100 to 107 in ed897b7

	if is-active tarnish; then
	echo "Stopping tarnish"
	systemctl stop tarnish
	fi
	if is-enabled tarnish; then
	echo "Disabling tarnish"
	systemctl disable tarnish
	fi

This should probably be made into a command in install-lib to avoid repetition.
