Add tests for multiline batches

Some related tests for generic c2s batches were shoved in here as well
for lack of a better spot to put them.

This change required actually bringing extension modules into the unit
test runtime. This was easier for meson since we could just update the
existing shell script, but for autotools I brought dependencies
specifically on the extension .so files needed for tests (as relying on
everything in patsubst like we do for core/autoload modules would
attempt to depend on filter.so even on systems where libhs isn't
available, which would fail the build).
