stress-ng: Add recipe

A tool to generate load and stress a system, currently this recipe
is on a couple of layers [1] and is not updated, a good reason to
have in meta-oe.

+Subject: [PATCH] Several changes to fix musl build
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+stress-{context, stackmmap}.c: Set tests to non-implemented because uses
+swapcontext, musl provide the definition but not the implementation due
+  to that functions are pre-POSIX and set to be deprecated.
+  stress-{resources, pty}.c: Doesn't include termio.h and remove stress
+  operations that uses struct termio, musl doesn't provide that struct.
+stress-pthread.c: Change pthread_yield to sched_yield to be more compatible.
+stress-malloc.c: Check for definition of M_MMAP_THRESHOLD musl doesn't
+  ptovide that constant.
+stress-madvise.c: Add static poision_count integer, definition of
+  MADV_SOFT_OFFLINE doesn't grauntee MADV_HWPOISON to be defined.
+cache.c: Define GLOB_ONLYDIR not available on MUSL.
