apps/examples/pipe: check POSIX-compliant behavior of NuttX's FIFOs
Adjust the test considering the POSIX-compliant behavior of the NuttX's FIFO (mkfifo), which should block `open` for read-only and write-only. This test's result is expected to be the same with any other POSIX-compliant system. This commit also: * Fix redirect test; * Use pthread instead `task_create` to be able to run this test on POSIX-compliant systems; * General fixes regarding formatting and error messages;
