Subject: [PATCH] trivial-httpd: Add __attribute__((format))

I was briefly looking at building with clang mostly since it
detects unused variables with cleanup attributes, but then
I hit this fatal error.

It's a hard compile error with `-Wformat-nonliteral` since clang
doesn't know it's a format string.
