Tiago Medicci Serrano 4d6a8663fa drivers/pipe: make pipe and named pipe (mkfifo) POSIX-compliant ...

According to https://pubs.opengroup.org/onlinepubs/9699919799/functions/open.html

"
 When opening a FIFO with O_RDONLY or O_WRONLY set:
  * If O_NONBLOCK is set, an open() for reading-only shall return
    without delay. An open() for writing-only shall return an error
    if no process currently has the file open for reading.

  * If O_NONBLOCK is clear, an open() for reading-only shall block
    the calling thread until a thread opens the file for writing.
    An open() for writing-only shall block the calling thread until
    a thread opens the file for reading.

This commit has an equivalent on nuttx-apps: EXAMPLES_PIPE app
was updated to be able to check pipes and named pipes behavior.
