topdir.mk: Move PREREQ definition into defs.mk

Browse source 
At present, the PREREQ-variable is effectively only used to detect if
prerequiste packages haven't run "make all" before make is run in a
given package. Also, it's only useful in $(TOPDIR). This commit
splits the variable up into PREREQ_BUILD and PREREQ_RUN, and makes
the variables available in every Makefile of a package by placing
them in defs.mk instead of topdir.mk.

This also fixes a problem that PREREQ was cached before being filled,
hence empty. Which effectively wasn't much of a problem, because it
was basically unused, but still.
