tools_test: Clean up and fix sysfs_l3_parity

Multiple misunderstandings of the expectations of the test and some
missed parts of the shell-to-c conversion caused a couple of issues to
remain.

First, we need to actually disable a subbank before we check that a
subbank is disabled (invoke the tool with -d).

Second, the original pipe to wc -l was to check that the tool prints
only one line, not that it prints "at least" a line. Modify the last
check to verify that an "is disabled" text is _not_ printed.

v2: Add a TODO comment
