I'll add it to 'runtest/cve' but will leave it in the syscalls/keyctl directory.
I don't like the idea of putting "CVE regression tests" in a separate directory
because then it will be harder to find all the tests for a given syscall or

It's including the Linux UAPI header (from include/uapi/linux/keyctl.h), not
even the libkeyutils header.  Is using UAPI headers really not allowed in LTP?
I see tons of other tests that include <linux/${foo}.h>.
