If the passed-in shader references RTFlip (i.e., sk_FragCoord is used), the settings must contain RTFlip layout info; otherwise, an error occurs. Originally, the fuzzer detected this as a problem because the error was being delivered via SK_ABORT, but it's failing more cleanly now that Ethan's new error handling code is in place (causing the fuzzer to report that the bug was "fixed"). With this CL, the oss-fuzz shader will actually compile successfully in SPIR-V instead of leading to an error.
