package-modules: use && instead of ; between copy commands

Using ; to join commands in a rule causes failures to be ignored by
make.  Use && instead, and add true at the end as the second operand
to the last && operator.

Also inline copy-test-in-batch, batching is no longer necessary as
kati will fall back to a shell script if the recipe is too long to
fit in a command line.

Test: builds
