docs: clarify <packagename>_PATCH behaviour

Reiterate once more that <packagename>_PATCH variable can point
to an arbitrary URL, not just to a path relative to <packagename>_SITE.

While we're at it, also explain that the patch should be added to the
.hash file.

[Arnout: add sentence about .hash file.]
