[PATCH 2/2] ref-manual/variables.rst: document the PACKAGEFUNCS variable

[Antonin Godard <antonin.godard@bootlin.com>]

Added by commit 4b46c1f6e891 ("Initial population") in OE-Core. This
completes the variables used during do_package, as
PACKAGE_PREPROCESS_FUNCS and PACKAGESPLITFUNCS are already documented.
