macro: add new helper RET_NERRNO()
This new helper converts libc style syscall return values into
systemd-kernel (actually: kernel style) negative errno values.
It's implemented as macro-like inline function, and propagates return
values >= 0 as themselves and returns -errno for negative error returns.
THis is supposed to be little more than syntactic sugar so that we can
reduce a lot of (short, but still) boilerplate code whever we convert
libc style error handling into our own.
