meson: Don't check for posix_memalign on windows
There's a mingw bug for this, it exports __builtin_posix_memalign but not posix_memalign, so the check will succeed, but compiling will fail. Reviewed-by: Eric Engestrom <eric.engestrom@intel.com> Acked-by: Kristian H. Kristensen <hoegsberg@google.com>
