Some programs[1] try to use io_uring, which is considered
by many[2] to be a security risk. Therefore I implemented it
as returning EPERM, as is done by the linux kernel in case
of a security restriction.
The advantage of this patch is it reduces noisy output over
the 'not implemented' situation.
1: in my case: cmake.
2: Google, OpenSUSE, Docker, RockyLinux at the very least
had discussions about disabling io_uring.
