Title: don't treat Makefile as an indicator of the project root

Sadly, despite recursive make well-known to be harmful, it is still in common
use, which means that the presence of Makefile in a directory cannot reliably
indicate that that directory is the root of a project. Therefore it is safer
not to include this in projectile-project-root-files by default.
