bf91b0ed ("tests/build: Allow to define per-test parameters via a dict")
turned drivers_tests into a dict and updated the loop that defines the real
tests, but the fallback that only adds the skipping ones still asks for a
single iteration variable. Configuring with -Dintrospection=false stops right
there:
tests/meson.build:295:25: ERROR: Foreach expects exactly 2 variables for
iterating over objects of type dict
Hit it with meson 1.11 while building a single driver without introspection.
