Makefile.mk: Fix inclusion of site-local/Makefile.inc

In commit 854dd9a5d1153fbb7ace2a7619bb98d024e284ce
(Makefile.mk: Put site-local path first) the inclusion of
site-local/Makefile.inc was moved to the first place. Unfortunately,
the very next line where subdirs-y is modified resets the variable
instead of extending it which overwrites the inclusion of
site-local/Makefile.inc. This breaks setups where
site-local/Makefile.inc is required.

This patch fixes it.
