wic/engine: dump the partition table in JSON format only

since commit 03154d2cf25c1d5ce908da9e72d324004b8d5722 ("sfdisk: add -J between mutually exclusive options")
in util-linux [1], the '-J' can't be used with the '-d' option anymore.

So, since we're using json format output, drop the '-d' option.

Fixes:

ERROR: _exec_cmd: <snip>/usr/sbin/sfdisk -dJ <snip>/core-image-minimal-qemux86-64.wic returned '1' instead of 0
output: sfdisk: mutually exclusive arguments: --list-free --json --dump
