sys/linux/test: test case for bpf_trace_printk description
This commit adds a new test case for the bpf_trace_printk description introduced in the previous commit. It corresponds to the code: bpf_trace_printk("%d ", 8, 0x1234); exit 0; in a BPF program that is then executed via BPF_PROG_TEST_RUN. Signed-off-by: Paul Chaignon <paul.chaignon@gmail.com>
