conf: domaincaps: Fix broken attempt at being const-correct

'virBlahPtr const blah' results into modification to the value of 'blah'
triggering compilation error rather than the modification of the virBlah
struct the pointer points to.

All of the domain capability formatting code was broken in this regard.
