Karol Kosek d1328639b4 mkfifo: Don't rely on global errno
Core::System::mkfifo() doesn't rely on POSIX's mkfifo() and sends the
syscall directly to our system. This means that the and errno doesn't
get updated which ultimately caused the program to display an incorrect
message 'mkfifo: Success (not an error)'.
