build.py: Honour flavour argument of prereq command

This commit also abandons make echo-prereq in the project's directories, which
is too unspecific to achieve the point of this commit.

It has the following consequences:

- All PREREQ_XXX definitions in makefiles become meaningless
- Build order can break, because it now solely relies on project.conf
