[ndctl PATCH 1/2] ndctl, test: fix tests for the array vs object listing fix

[Vishal Verma]

The commit below updated json listings to always be arrays unless,
potentially, --human was specified. As a fallout of the change, some
unit tests that used jq to look for certain elements, or the json2var
conversion broke in certain cases. Fix the jq query in sector-mode.sh,
and fix json2var in test/common. The 'destructive' class of unit tests
still need to be converted to the test/common scheme, and subsequently
have their own local json2var instances. These will be fixed in a future
commit by simply performing the test/common conversion.

Fixes: 72c46ab194d9 ("ndctl list: always output array without --human")

[ndctl PATCH 2/2] ndctl, test: convert remaining tests to use test/common

[Vishal Verma]

The original test/common conversions missed the --enable-destructive
class of tests. The json single object vs. array changes prompted
changes to the json2var definitions, which these tests had a local copy
of. Instead of fixing up these local copies, take the change to properly
convert these tests to using test/common.
