Revert of Pepper: Refactor OpenManifestEntry. (https://codereview.chromium.org/302093012/)

Reason for revert:
This broke NaClBrowserTestPnaclNonSfi.IrtManifestFile on linux 32. That test will have to pass on the right trybot before landing. I'm not sure why it broke yet.

Original issue's description:
> Pepper: Refactor OpenManifestEntry.
> 
> This change pulls out more OpenManifestEntry code from service_runtime, making
> PPB_NaCl_Private a smallter interface, and preparing for pulling all of that
> logic out of the trusted plugin.
