[PATCH 5.9 152/757] selftests/seccomp: Use __NR_mknodat instead of __NR_mknod

[Greg Kroah-Hartman]

From: Kees Cook <keescook@xxxxxxxxxxxx>

[ Upstream commit 05b52c6625278cc6ed1245a569167f86a971ff86 ]

The __NR_mknod syscall doesn't exist on arm64 (only __NR_mknodat).
Switch to the modern syscall.
