[PATCH liburing v1] liburing: Export `__NR_io_uring_{setup,enter,register}` to user

[PATCH liburing v1] liburing: Export `__NR_io_uring_{setup,enter,register}` to user

[Ammar Faizi]

These macros are not defined in a old <sys/syscall.h> file. Allow
liburing users to get io_uring syscall numbers by including
<liburing.h>.
