Subject: [PATCH] [BUGFIX lts] Fixes a regression in the legacy build

For some reason, the 'transform-template-literals' plugin is now required even
in our standard non-evergreen builds. We really just need to finish up making
ember-source an addon, but this should fix people's builds for the time being.
