[clang] Fix test on read-only file systems (PR #205108)

[Walter Lee via cfe-commits]

https://github.com/googlewalt created https://github.com/llvm/llvm-project/pull/205108

Fixes 25e4057d49055a645dc6a51ae1f40ac647aaed5b.

Use the -fsyntax-only flag instead of -c.  This performs the necessary parsing and diagnostics verification (the actual intent of this test) without attempting to emit an object file.
