migration-guides/migration-5.1.rst: correct S/UNPACKDIR patterns for file-only recipes

It is not necessary to set both; just setting S to UNPACKDIR is enough.

This has already been done across oe-core master, and correct advice
should be given for those who need to adjust recipes during migration.

 If a recipe has :term:`S` set to be :term:`WORKDIR`, this is no longer
 supported, and an error will be issued. The recipe should be changed to::
 
-    S = "${WORKDIR}/sources"
-    UNPACKDIR = "${S}"
+    S = "${UNPACKDIR}"
 
 Any :term:`WORKDIR` references where files from :term:`SRC_URI` are referenced

 Building C files from :term:`UNPACKDIR` without setting :term:`S` to point at
 it does not work as the debug prefix mapping doesn't handle that.
