Verify format specifiers in bpf_trace_printk in rewriter

Verifies format specifiers while rewriting calls to bpf_trace_printk
and prints a warning the printk will be rejected by the kernel at
runtime.

For tests, redirects stderr at the file descriptor level in order to
catch warnings from the C library.
