[LTP] [PATCH v2] getrandom: Add negative tests for getrandom

[Petr Vorel]

Hi Yang Xu, Avinesh,

FYI this broke in CI. Using <sys/random.h> without m4 check broke old libc
(glibc < 2.25 or musl < 1.1.20). I suggest to ignore kernel < 3.17 (we still
have 3.10 support in docs although it's not CI).

I'm on travelling, but I'll should manage to send patch today.

Kind regards,
Petr
