virsh: Reject negative numbers in vshCommandOptUL

Browse Source 
To follow the new semantics of the vshCommandOptToU* functions convert
this one to reject negative numbers too. To allow using -1 for "maximum"
semantics for the two bandwidth functions that use this helper introduce
vshCommandOptULWrap. Although currently the migrate-setspeed function
for the qemu driver will reject -1 as maximum.
