block: Enable BDRV_O_SNAPSHOT with driver-specific options
In the case of snapshot=on, don't rely on the backing file path in the
temporary image any more, but override the backing file with the given
set of options. This way, block drivers that don't use a file name can
be accessed with snapshot=on, for example:
-drive file.driver=nbd,file.host=localhost,snapshot=on
Which becomes internally something like:
file.filename=/tmp/vl.AWQZCu,backing.file.driver=nbd,backing.file.host=localhost
