spicec: Make loglevel configurable through the environment

Having a loglevel variable is much more useful if we can actually change
its value without a recompile. Use a SPICEC_LOG_LEVEL environment variable so
we can do this from the spice xpi / activex too (by setting the environment
variable before starting the browser).
