Catch and discard any exception thrown in getWebViewNativeLibraryPaths to avoid the system server crashing if there is something wrong with the update APK. prepareWebViewInSystemServer(nativePaths) is safe to call even if nativePaths is null or invalid, and must be called to ensure that any process waiting for relro processing is unblocked.
