[PATCH 4/4] libtests/malloctest/init.c: Fix warning

[Joel Sherrill]

posix_memalign() is prototyped to take a non-NULL parameter. But our
test is deliberately passing one in. With the -Wnon-null warning flag
enabled, we will always get warnings on this test unless we disable
that warning for this single test case.
