I think that this can be done by changing https://cs.chromium.org/chromium/src/tools/mb/mb_config.pyl?l=613 from release_bot to release_trybot.

Note, this will make the results similar to linux_chromium_rel_ng (both will hit DCHECK), but DCHECKs are disabled on the continuous release bots.

Do we want to do this because we want this try bot to be similar to linux_chromium_rel_ng?

Seems that the bot can't ignore so many unexpected crashes...
