virsh: Fix debugging

Commit a0b6a36f "fixed" what abfff210 broke (URI precedence), but
there was still one more thing missing to fix.  When using virsh
parameters to setup debugging, those weren't honored, because at the
time debugging was initializing, arguments weren't parsed yet.  To
make ewerything work as expected, we need to initialize the debugging
twice, once before debugging (so we can debug option parsing properly)
and then again after these options are parsed.

As a side effect, this patch also fixes a leak when virsh is ran with
multiple '-l' parameters.
