qemu: block: Extract formatting of 'driver' attribute from child formatters

Browse Source 
To allow reusing the formatters in the code for creating JSON properties
for 'blockdev-create' we need to create everything except the 'driver'
attribute.

Use the new helper virJSONValueObjectPrependString to put the driver at
the same place so that we don't change any output.
