Justin Suess c2fe8b60b8 landlock: Check landlock_restrict_self(2)'s flags before privileges ...

landlock_restrict_self(2) currently checks the no_new_privs /
CAP_SYS_ADMIN requirement before validating the flags argument.  An
unprivileged caller without no_new_privs thus gets EPERM even when the
passed flags are invalid, hiding the EINVAL error.

Move the no_new_privs / CAP_SYS_ADMIN check just after the flags check
so that malformed calls consistently error out with EINVAL whatever the
caller's privileges, the same way seccomp(2) validates its flags before
checking no_new_privs.

Update the restrict_self_checks_ordering test accordingly.
