Fix Hermes + no Flipper build on Xcode 12.5

Summary:
This is a follow up to my diffs from a couple weeks ago bumping folly version to 2021.04.26. Unfortunately, those diffs did not work when Hermes was enabled, and Flipper was disabled, this fixes that.

I've tested the matrix of Hermes enabled/disabled and Flipper enabled/disabled.
