printed manuals: xrefs in and out of "Preparing Patches"

Fix two cases of links where the on-line manual is one document but the
manual is split into separate documents for printing:

* doc/emacs/package.texi (Fetching Package Sources): fix printed link to
"Preparing Patches" to point to separate document.
* doc/emacs/vc1-xtra.texi (Preparing Patches): fix printed link to
"Directory Variables" to point to separate document.
