[PATCH] D29536: [libFuzzer] Don't add newline character when using echo in tests.

[Marcos Pividori via Phabricator via llvm-commits]

mpividori created this revision.

I add the option "-n", so we don't add a new line character at the end of the file when using echo. (on Windows this means 2 characters).
