mozinfo should report "serviceworker_e10s" if the "dom.serviceWorkers.parent_intercept" preference is set to true, which you would do via "--setpref".  Here's where the logic happens in:

- mochitests: https://searchfox.org/mozilla-central/rev/4587d146681b16ff9878a6fdcba53b04f76abe1d/testing/mochitest/runtests.py#2545
- xpcshell tests: https://searchfox.org/mozilla-central/rev/4587d146681b16ff9878a6fdcba53b04f76abe1d/testing/xpcshell/runxpcshelltests.py#1202

That said, running on try and including the "-sw" substring builds via the fuzzy builds is the easiest way to make sure you've got builds with that preference set.  (And that way you also get normal child-intercept tests to run too, they're the ones with "-sw" in them.)
