madvise.2: document reliable probe for advice support
EINVAL is an overloaded error code for madvise(2) and it's not clear
under what context it means "advice is not valid" vs another error.
Explicitly document that madvise(0, 0, advice) can reliably be used to
probe for kernel support for "advice", returning zero iff "advice" is
supported by the kernel.
