Makefile: don't use "FORCE" for tags targets
Remove the "FORCE" dependency from the "tags", "TAGS" and "cscope" targets, instead make them depend on whether or not the relevant source files have changed. For the cscope target we need to change it to depend on the actual generated file while we generate while we're at it, as the next commit will discuss we always generate a cscope.out file.
