test: tag integration suite :slow and unstick test-all

I tagged the 15 end-to-end tests across `test-integration-chime-mode.el`,
`test-integration-recurring-events-tooltip.el`, and
`test-integration-startup.el` with `:tags '(:slow)`. The default `make test`
now runs only the 652 fast unit tests; `make test-all` runs the full 667.

While verifying, I hit a pre-existing bug in `tests/Makefile` where
`test-all`'s `--eval '(ert-run-tests-batch-and-exit)'` came back from eask's
argv passthrough with its quotes stripped, which broke shell parsing. Passing
the explicit `t` selector dodges whatever eask does to no-arg single-quoted
forms. The bug only mattered once integration tests were `:slow` — before
that, `test-all` overlapped fully with `test-unit` plus `test-integration`,
so nothing actually depended on it working.
