Ivan A. Kosarev e73af512a6 [Safestack] Fix the canary test to catch the libc's message regarding stack smashing 
By default glibc writes its diagnostics directly to tty so the `2>&1 |`
redirection in the test doesn't catch the *** stack smashing detected ***
message, which in turn breaks printing the lit's progress bar. By defining
the LIBC_FATAL_STDERR_ environment variable we force glibc to direct
diagnostic messages to stderr.
