Add nonnull annotation to posix_memalign.

GCC 6.0+ asserts that the memptr argument to the builtin function
posix_memalign is nonnull.
Add the necessary annotation to the prototype and
remove the now unnecessary check to fix a warning.

newlib/Changelog
newlib/libc/include/stdlib.h: Annotate arg to posix_memalign as
non-null.

winsup/cygwin/ChangeLog
