add test for stdlib-migration: arrow

almost all outputs gain a host dependence on stdlib (including `apache-arrow-proc`,
where we insert the host section due to the assumption that an output without a
build section is relying on the global build requirements).

Note that `libarrow-all` does not gain a stdlib-dependence, as it _has_ a non-empty
build section.
