Mark this coreApp as being encryptionAware.

Historically, apps marked with "coreApp" were prepared to run in a
limited boot environment, and were critical to booting the device, so
in the new file-based encryption world we're marking these apps with
both "forceDeviceEncrypted" and "encryptionAware" attributes.
