[MC] Plumb unique_ptr<MCMachObjectTargetWriter> through createMachObjectWriter

to MCObjectWriter's constructor.

MCObjectWriter takes ownership of its MCMachObjectTargetWriter argument -- this
patch plumbs that ownership relationship through the constructor (which
previously took raw MCMachObjectTargetWriter*) and the createMachObjectWriter
function.
