testplan/meson.build: disable kms check testlist if not chamelium

The KMS JSON file contains some tests that can optionally be disabled.
When those are disabled, the code can't check for missing documents,
as the JSON file specifies both enabled and disabled tests.

Detect that to avoid build problems.

While here, remove a left-over dictionary (xe_test_dict).
