[LTP] [PATCH 3/3] syscalls/shmat03.c: add new regression test

[Richard Palethorpe]

Hi,

Oops, this is practically the same as my test cve/CVE-2017-5669.c. We may have
to start annoucing that someone is working on particular regression to
avoid duplication.

Cyril can you apply the safe macro patch?
