tools: virt-admin: do not leak daemon-log settings

The commands daemon-log-filters and daemon-log-outputs
are used both for getting and setting the variables.
But the getter receives an allocated string, which
we do not free.

Use separate variables for the getter and the setter
to get rid of the memory leak and to stop casting
away the const.
