LOG: llvm-reduce: Fix missing newline after error message

Fixes missing test coverage for the failed to execute case. However,
this test fails to verify the newline is printed. I can't figure out
how to get FileCheck to match the trailing newline.

Added: 
    llvm/test/tools/llvm-reduce/fail-execute-test.test

Modified: 
    llvm/tools/llvm-reduce/TestRunner.cpp

Removed:
